Article 2 of 5 — Cement Industry

How Khash Would Implement ICML 55 Lubrication Management in a Cement Plant Through Noria-Style Consulting and Service Programs

I will continue using Khash as the lubrication-management implementation lead or consultancy program owner. This article is written for a full cement operation, from quarry to dispatch, and maps ICML 55 requirements into a Noria-style consulting/service delivery model.

1. Strategic intent: why cement plants need a formal lubrication-management system

A cement plant is one of the most contamination-intensive industrial environments for lubricated machinery. Lubricants are exposed to cement dust, clinker dust, limestone dust, gypsum dust, coal dust, high temperature, shock loading, slow-speed heavy-load contact, high-speed fans, large open gears, kiln heat transfer, vibration, washdown, outdoor storage, and long operating campaigns.

The lubrication problem in cement is not that the plant has too many exotic machines. The problem is that ordinary bearings, gearboxes, chains, hydraulic systems, compressors, blowers, and fans are operating in an aggressive environment where small lubrication errors become expensive failures. Cement-industry lubrication guidance emphasizes that cement plants contain many diverse lubricant applications and that success depends heavily on selecting the correct lubricant type, method, and frequency of application rather than relying on generic lubrication habits. (Machinery Lubrication India)

ICML 55 is a strong framework for cement plants because it converts lubrication from a maintenance activity into a managed asset-reliability system. ICML describes ICML 55 as lubrication-specific standards introduced to define requirements and guidelines for effective, audit-ready management of lubricated mechanical assets, aligned with ISO 55000 physical asset-management principles. (Lubrication Council) ICML 55.1 defines what should be done, while ICML 55.2 explains how to implement the requirements in a way that can be customized to the organization. (Lubrication Council)

For Khash, the cement-industry objective should be:

To build a governed lubrication-management system that reduces lubrication-related failure in crushers, mills, kiln drives, open gears, hydraulic systems, fans, conveyors, compressors, packing equipment, and mobile quarry assets by controlling lubricant selection, contamination, application, inspection, analysis, task execution, competency, documentation, RCA, and continuous improvement.

2. Cement plant lubrication philosophy under ICML 55

The cement plant should not be managed only by calendar-based oil changes and traditional greasing rounds. Khash should implement lubrication as a controlled lifecycle:

Lubricant specification
Procurement and approval
Receipt inspection
Storage and handling
Transfer and filtration
Application to the machine
Inspection and sampling
Condition monitoring
Corrective action
Reclamation or disposal
Root cause analysis
Program audit and management review

This lifecycle matches ICML 55’s intent: a sustainable lubrication-management system integrated into asset management, not a collection of disconnected PMs. ICML’s current public description states that ICML 55.1 has a comprehensive view of twelve interrelated areas of a world-class lubrication program plan. (Lubrication Council)

For cement, the most important ICML 55 themes are:

ICML 55 area	Cement-specific interpretation
Lubrication-management objectives	Reduce kiln, mill, crusher, fan, gearbox, hydraulic, and conveyor failures.
Competency	Train lube technicians, millwrights, kiln crews, quarry maintenance, planners, reliability engineers, and operators.
Machine readiness	Install breathers, sample ports, filter connectors, sight glasses, drains, guarded access points, and open-gear inspection windows.
Lubricant selection	Define correct oil, grease, open-gear lubricant, hydraulic fluid, compressor oil, chain oil, and specialty products by duty.
Planned tasks	Engineer greasing volume, frequency, route sequence, safety requirements, and condition-based oil changes.
Storage and handling	Prevent dust, water, and cross-contamination from receipt to point of use.
Inspection	Standardize operator and lubrication-technician inspections for oil level, leakage, contamination, temperature, pressure, noise, spray patterns, and grease purge.
Condition monitoring	Use oil analysis, grease analysis, wear debris, thermography, vibration, ultrasound, and online sensors.
Troubleshooting and RCA	Investigate repeated bearing, gearbox, hydraulic, kiln-drive, open-gear, and fan failures.
Waste and environment	Reduce leakage, oil disposal, unnecessary changeouts, excess grease purge, and contaminated-water risk.
Metrics	Track compliance, cleanliness, water, oil-analysis health, route quality, lubricant consumption, and lubrication-related downtime.
Audits and management review	Maintain auditable evidence that the lubrication program is controlled, reviewed, and improved.

3. Noria-style consulting delivery model for cement plants

Khash should implement the cement lubrication program through a phased consulting and services model similar to Noria’s Lubrication Program Development approach. Noria describes LPD as a three-phase model: Ascend Assessment, Engineering Design, and Program Implementation. Its public LPD page describes the assessment as a 543-point benchmark with a roadmap and cost-justification report; the engineering phase includes standard procedures, calculated volumes and frequencies, and lubricant/hardware recommendations; the implementation phase includes team training and lubrication-route design in lubrication-management software. (Noria Corporation)

Noria also lists typical phase durations as approximately one week for Phase I Ascend Assessment, six to eight weeks for Phase II Engineering Design, and one to two years for Phase III Implementation. (Noria Corporation)

3.1 Phase 1 — ICML 55 / Ascend baseline assessment

Khash should begin with a plantwide lubrication-management assessment. The assessment should not be only a lube-room inspection; it must cover the entire cement process:

Quarry
Primary and secondary crushing
Raw-material handling
Raw mill
Coal mill or petcoke grinding system
Preheater and calciner
Rotary kiln
Kiln drive and support rollers
Clinker cooler
Clinker transport
Cement grinding
Roller press or vertical roller mill
Cement silos
Packing plant
Bulk loading
Utility systems
Mobile equipment
Waste heat recovery, where installed

The assessment should evaluate:

Lubricant selection
Lubricant consolidation opportunities
Greasing practices
Oil-change criteria
Oil-analysis program quality
Open-gear lubrication condition
Kiln support roller lubrication
Mill gearbox lubrication
Crusher bearing lubrication
Fan bearing lubrication
Hydraulic cleanliness
Storage and handling quality
Lubricant transfer practices
Breather condition
Filtration practices
Sampling hardware
Sample procedure quality
CMMS PM accuracy
Route compliance
Operator inspection quality
Contractor lubrication practices
Lubricant waste and leakage control
Training and competency gaps
RCA discipline
Program metrics

A useful cement-specific note is that Noria’s public LPD page references an Argos Cement Plant case where Noria training and an Ascend Assessment helped identify better lubricant handling options, more effective greasing techniques, and contaminant exclusion/removal opportunities. (Noria Corporation) That is very close to what Khash should replicate: not merely recommending lubricants, but redesigning how lubrication is handled, applied, verified, and sustained.

4. Cement plant asset segmentation and lubrication risk map

Khash should not treat all equipment equally. The plant should be divided into lubrication zones, each with different failure modes and controls.

4.1 Quarry and raw-material extraction

Dust collectors
Baghouse fans

Dominant lubrication risks:

Shock load

poor sealing around reducers

Khash’s controls:

Select crusher lubricants by OEM requirement, bearing type, shock load, sump temperature, and contamination exposure.
Use grease with suitable base-oil viscosity, EP performance, mechanical stability, and dust resistance.
For slow-speed crusher bearings, avoid using generic multipurpose grease when a higher-viscosity, heavy-duty grease is required.
Use purgeable bearing arrangements where contamination is unavoidable.
Apply ultrasound-assisted greasing on medium- and high-speed bearings to prevent overgreasing.
Install desiccant breathers on crusher gearboxes and hydraulic units.
Use offline filtration carts or permanently installed kidney-loop systems for large crusher gearboxes.
Add sample ports to crusher lubrication systems and define alarm limits for water, particle count, viscosity, and wear metals.
Inspect crusher lubrication systems after every major liner change or rebuild because contamination often enters during maintenance.

4.3 Raw mill and raw grinding area

Typical assets:

Vertical roller mills
Ball mills
Mill main gearboxes
Grinding rollers

mill fan bearing failures
lubricant starvation in grinding roller bearings

Khash’s controls:

Treat the raw mill gearbox as an A-class lubrication asset.
Install high-efficiency breathers, filter connectors, sight glasses, level gauges, and representative sample ports.
Use gearbox oils selected by OEM specification, viscosity, load, operating temperature, micropitting risk, filterability, and compatibility.
Use offline filtration for mill main gearboxes and maintain particle cleanliness targets.
Use periodic or continuous oil analysis for viscosity, oxidation, water, acid number, particle count, PQ index, ferrous debris, and elemental wear metals.
Evaluate varnish or deposit risk in high-temperature circulating systems.
For hydraulic tensioning systems, set cleanliness targets based on valve sensitivity.
Use pressure-line and return-line filtration with differential-pressure monitoring.
Use live-zone sampling upstream of filters for wear diagnosis and downstream sampling where filtration performance must be checked.

Khash’s controls:

Coordinate lubrication work with plant fire, explosion, and hot-work controls.
Use leak-elimination and oil-mist housekeeping standards in coal/petcoke areas.
Keep lubricant containers sealed and electrically/operationally suitable for the area classification.
Avoid open oil transfer and open funnels.
Maintain gearbox oil cleanliness and water control.
Include coal mill lubrication points in safety-critical PM audits.

Kiln support rollers
Kiln thrust rollers
Support roller bearings
Trunnion bearings
Kiln tyre contact areas
Kiln hydraulic thrust system
Kiln inlet and outlet seals
Kiln lubrication spray system
Kiln shell cooling fans
Kiln drive couplings

This is one of the highest-value areas of the lubrication program. Cement-industry lubrication guidance identifies many open gears in cement plants, especially ball mills and rotary kilns, and stresses that open-gear lubricants must adhere for the gear revolution, be applied correctly to the mating teeth, and have suitable load-carrying ability and body. (Machinery Lubrication India) The same source notes that rotary kilns create lubrication challenges because of slow rotation, high loading, and heat transfer from the process, and that kiln gearbox oil often uses circulation with heat transfer and filtration. (Machinery Lubrication India)

Khash’s kiln lubrication controls

Kiln girth gear and pinion

Khash should create a dedicated open-gear lubrication standard covering:

Approved open-gear lubricant
Viscosity or consistency range
Base oil and additive type
Load-carrying performance
Adhesion and tackiness
Pumpability through spray system
Spray nozzle type
Spray frequency
Spray duration
Spray pattern
Tooth-flank coverage
Film thickness inspection
Root and flank deposit control
Pinion/girth gear alignment checks
Gear temperature monitoring
Wear-pattern inspection
Cleaning method
Used lubricant and overspray control

The open-gear system should not be judged only by lubricant consumption. Khash should verify:

Whether the spray nozzles hit the correct tooth region
Whether spray timing is synchronized with gear rotation
Whether the lubricant covers the full face width
Whether there is dry flank contact
Whether there is excessive buildup at the tooth root
Whether root buildup is causing hydraulic wedging
Whether pinion misalignment is creating edge loading
Whether the lubricant is being thrown off before meshing
Whether dust is forming abrasive paste
Whether inspection frequency is sufficient

The cement lubrication article specifically notes that spray pattern is critical for open gears because coverage of mating teeth must be sufficient. (Machinery Lubrication India) Khash should make spray-pattern verification a routine PM, not a one-time commissioning check.

Kiln support roller and thrust roller bearings

Khash should define:

Oil or grease type by bearing design
Minimum oil viscosity at operating temperature
Heat-transfer requirement
Cooling-water or air-cooling requirement
Seal inspection frequency
Bearing temperature alarm limits
Oil-analysis frequency
Water and particle limits
Sampling point location
Drain and flush procedure
Alignment-related failure triggers

Common kiln support roller failure modes to manage:

Lubricant starvation
viscosity loss due to heat
dust ingress
water ingress from cooling or washdown
misalignment-induced loading
bearing overload
seal failure
lubricant oxidation
abrasive wear
oil-level mismanagement
incorrect lubricant substitution

Kiln main gearbox

Khash should treat the kiln main gearbox as a critical asset requiring:

Dedicated lubricant specification
Filtered filling and top-up
Desiccant breather
offline filtration
sample ports
oil-level monitoring
thermal inspection
vibration integration
oil-analysis alarm limits
shutdown inspection criteria
borescope inspection where possible
magnetic plug or magnetic separator review
condition-based oil replacement

The oil-analysis slate should include:

Viscosity at 40°C and/or 100°C

Hydraulic cylinders
Gearboxes
Lubricated rollers and wheels

Dominant lubrication risks:

High radiant heat
clinker dust
shock load
abrasive particles
slow-moving chains
high vibration
grease hardening
thermal degradation
poor access
frequent leakage
excessive lubricant consumption

Cement-industry lubrication guidance notes that slow-moving clinker conveyors can operate in dusty and hot conditions and may require frequent greasing; it also describes automatic systems that travel with bucket wheels and need regular planned-maintenance checks because of their moving parts and sensors. (Machinery Lubrication India)

Khash’s controls:

Use high-temperature greases where bearing temperature requires them.
Use chain lubricants selected for temperature, penetration, evaporation resistance, and dust handling.
Inspect grease purge for carbonization, hardening, dust loading, and lack of fresh grease.
Verify automatic greasing system function using pressure response, injector movement, sensor feedback, and physical purge checks.
Install remote grease points where access is unsafe.
Protect grease lines from heat, falling clinker, vibration, and mechanical damage.
Audit lubrication task safety because cooler and clinker transport areas are high-risk access zones.
Use thermography to identify overheated bearings and blocked lubrication paths.

4.7 Finish grinding: cement mills, roller presses, and separators

Typical assets:

Ball mills
Vertical cement mills
Roller presses
Main gearboxes

fan bearing failures
oil leaks into dusty areas
separator bearing temperature problems
high energy cost caused by friction and poor alignment

Ball mill lubrication

Ball mills often include large open gears, pinions, trunnion bearings, slide-shoe bearings, circulating oil systems, and auxiliary drives. Khash should implement:

Open-gear spray inspection routes
Pinion bearing oil or grease control
Trunnion or slide-shoe bearing oil analysis
Oil circulation filtration
oil cooler performance monitoring
water detection
gear-contact pattern inspection
high-viscosity lubricant handling procedure
mill start-up lubrication verification
interlock review for low oil pressure or high bearing temperature
shutdown inspection criteria

Roller press lubrication

Roller presses require strong lubrication governance because they combine high load, vibration, hydraulic force, and bearing sensitivity. Khash should implement:

Bearing grease or oil specification based on OEM design
hydraulic-fluid cleanliness targets
grease quantity and interval calculation
bearing temperature monitoring
shock-load review
seal inspection
contamination exclusion
oil analysis of hydraulic and gearbox systems
RCA on repeated bearing temperature alarms
grease-sampling program for expensive roller bearings where feasible

Separator and fan lubrication

High-speed separator and fan bearings are often damaged by overgreasing, poor grease selection, imbalance, contamination, and temperature. Khash should implement:

ultrasound-assisted greasing
calculated regrease volumes
grease-gun calibration
purge-path verification
vibration/temperature correlation
motor bearing procedures
fan bearing oil analysis where oil-lubricated
laser alignment and balance integration with lubrication RCA

4.8 Packing plant, dispatch, and loading systems

slide gates
gearmotors
baghouse fans

Dominant lubrication risks:

Cement dust
high cycling
small gearmotor neglect
pneumatic-system contamination
compressor lubricant degradation
missed lubrication points
product contamination risk
poor contractor maintenance

Khash’s controls:

Use small-asset lubrication routes with barcode or QR code verification.
Standardize gearmotor oils and greases.
Prevent overgreasing in small bearings.
Use sealed transfer containers for small top-ups.
Add packing plant equipment to the lubricated asset register rather than ignoring it as “minor equipment.”
Include compressors and blowers in oil-analysis routes.
Control compressor oil by discharge temperature, OEM requirements, oxidation, varnish, and filter performance.
Inspect air-line oil carryover where it affects packer reliability.

5. Lubricant selection and consolidation for cement plants

Cement plants often accumulate many lubricant SKUs because of OEM recommendations, local supplier influence, legacy habits, and emergency substitutions. Khash should rationalize the list, but not over-consolidate. Cement-industry lubrication guidance specifically notes that lubricant stock rationalization is common in large cement plants, but some applications require specialized lubricants whose higher initial cost may reduce unplanned downtime and extend equipment life. (Machinery Lubrication India)

5.1 Lubricant families in a cement plant

Khash should classify all lubricants into controlled families:

Lubricant family	Typical applications
Heavy-duty EP gear oils	Kiln drives, mill gearboxes, crusher reducers, conveyor reducers
Synthetic gear oils	High-temperature or energy-critical large drives
Circulating oils	Mill bearings, kiln support systems, large enclosed drives
Hydraulic oils	Mill hydraulics, roller press hydraulics, cooler hydraulics, mobile equipment
Fire-resistant hydraulic fluids	Coal mill or high-fire-risk areas where required by risk assessment
Compressor oils	Plant air compressors, instrument air compressors
High-temperature greases	Kiln, clinker cooler, hot conveyors, fan bearings near heat
Heavy-duty EP greases	Crushers, conveyors, quarry equipment, roller press bearings
Electric motor greases	Motors, fans, pumps, separators
Open-gear lubricants	Kiln girth gear, ball mill girth gear, large exposed drives
Chain oils	Clinker conveyors, bucket elevators, hot chains, process conveyors
Wire-rope lubricants	Cranes, hoists, quarry equipment
Specialty lubricants	Couplings, anti-seize compounds, sliding surfaces, seals

5.2 Technical selection criteria for oils

Each oil specification should define:

ISO viscosity grade
viscosity index
base oil type
additive chemistry
OEM approval
minimum viscosity at operating temperature
maximum operating temperature
oxidation stability
antiwear or EP performance
micropitting protection
demulsibility
air release
foam tendency
filterability
seal compatibility
paint compatibility
compatibility with existing oil
water tolerance
target cleanliness
oil-analysis limits
storage color code
transfer-container code
approved alternate

5.3 Technical selection criteria for greases

Each grease specification should define:

NLGI grade
base-oil viscosity
thickener type
dropping point
mechanical stability
water washout resistance
oxidation resistance
corrosion protection
EP and antiwear performance
pumpability through automatic systems
low-temperature mobility where applicable
high-temperature capability
compatibility with existing grease
relubrication volume
relubrication interval
purge requirement
bearing speed factor limit
storage method
grease-gun color code

5.4 Technical selection criteria for open-gear lubricants

Open-gear lubricants in cement are critical and should not be selected like normal grease. Khash should define:

method of application: spray, brush, drip, bath, or automatic system
pumpability through lines and nozzles
adhesion to gear teeth
load-carrying capacity
solid lubricant content, if used
film strength
base-oil viscosity
thickener or binder type
temperature capability
solvent or solvent-free formulation
environmental and housekeeping impact
inspection method
cleaning method
consumption target
compatibility with existing residues
gear-tooth inspection acceptance criteria

The cement lubrication article stresses that conventional greases are not suitable for certain open-gear applications because they do not have the required adhesion, body, sprayability, and load-carrying characteristics. (Machinery Lubrication India)

6. Contamination-control strategy

In cement, contamination control is the largest single lever in lubrication reliability. Khash should define contamination-control requirements at four boundaries:

Lubricant receipt
Lubricant storage
Lubricant transfer
Machine ingress control

6.1 Dust contamination

Cement dust is fine, abrasive, and pervasive. It enters through:

open breathers
damaged seals
poor hatch sealing
unsealed transfer containers
dirty funnels
grease fittings not cleaned before use
open drums
poor top-up practices
maintenance activities
negative-pressure or positive-pressure area effects
damaged bearing housings
open chain and gear systems

Khash should implement:

desiccant breathers or hybrid breathers
sealed reservoir hatches
quick-connect fill points
dedicated transfer containers
no open funnels
filter carts for top-ups
precleaned grease fittings
sealed grease-gun storage
dust-proof lube-room design
satellite lube cabinets
filter-breather upgrades
bearing isolators where appropriate
contamination-control audits after shutdown work

6.2 Water contamination

Water is less universal than dust in cement, but it is still important in:

quarry equipment

cooling systems
kiln support systems
hydraulic units exposed to washdown
compressors
fuel and mobile equipment systems
lube rooms with poor drum storage

Controls:

desiccant breathers
covered drum storage
bottom drains
BS&W bowls
sealed fill points
reservoir slope and drainability
crackle testing
Karl Fischer water testing
vacuum dehydration for critical systems
water-removal filter carts
heat-exchanger leak checks
oil-level inspection standards

6.3 Particle cleanliness targets

Khash should establish target cleanliness by asset class. These values must be finalized after OEM review, system sensitivity review, and asset criticality analysis, but useful starting targets are:

Asset class	Suggested starting ISO 4406 target
Servo/proportional hydraulic systems	15/13/10 or cleaner
Critical mill hydraulic systems	16/14/11 to 17/15/12
General hydraulic systems	18/16/13
Kiln main gearbox	18/16/13 or better
Mill main gearbox	17/15/12 to 18/16/13
Crusher gearboxes	18/16/13 to 19/17/14
Conveyor gear reducers	19/17/14
Fan bearing oil systems	17/15/12 to 18/16/13
Compressors	16/14/11 to 17/15/12
Open gears	Visual film, wear, debris, and spray-pattern control more important than ISO particle count

6.4 Filtration architecture

Khash should define filtration by system:

System	Recommended filtration control
Mill main gearbox	Permanent kidney-loop filtration or routine offline filtration
Kiln main gearbox	Offline filtration, magnetic debris control, routine sampling
Hydraulic systems	pressure/return filtration, offline filtration, differential-pressure indicators
Crusher gearboxes	portable filter-cart connection or fixed filtration for critical units
Fan bearing oil systems	offline filtration and clean top-up
Compressor systems	OEM filters, oil-analysis-based filter change, varnish/deposit monitoring
Bulk oil tanks	dedicated filtration loop and desiccant breather
Transfer to machine	filtered transfer through quick connects

7. Machine lubrication readiness

Khash should not expect technicians to perform precision lubrication on machines that are physically not ready for it. Machine readiness is a core part of implementation.

7.1 Hardware modifications for oil-lubricated cement assets

For critical gearboxes, hydraulic units, circulating-oil systems, and compressors, Khash should specify:

desiccant breathers
quick-connect fill ports
quick-connect filtration ports
live-zone sample ports
return-line sample ports where useful
filter differential-pressure gauges
sight glasses
columnar level gauges
bottom drains
magnetic drain plugs
magnetic separators where appropriate
BS&W bowls
reservoir inspection hatches
sealed reservoir covers
dedicated top-up fittings
offline filtration loops
moisture sensors on water-prone systems
particle counters for critical hydraulic systems
thermal sensors
oil-level alarms for critical systems

7.2 Hardware modifications for grease-lubricated cement assets

For grease points, Khash should specify:

clearly tagged grease fittings

clean or replace spray nozzles
verify spray-bar alignment
verify spray timing
check compressed-air quality where air-assisted spray is used
inspect gear guards
provide safe inspection access
create borescope or inspection-window access where needed
define safe cleaning method
define housekeeping limits for overspray and buildup
install lubricant drum management and low-level alarm
inspect lubricant heating system where high-viscosity product is used

8. Oil analysis, grease analysis, and condition monitoring

Khash should design the condition-monitoring program by failure mode.

8.1 Oil-analysis test slate by cement asset class

Asset class	Routine oil-analysis tests	Exception / advanced tests
Kiln main gearbox	viscosity, acid number, water, ISO particle count, elemental analysis, PQ index, FTIR oxidation	analytical ferrography, foam, air release, demulsibility, RULER if needed
Mill main gearbox	viscosity, acid number, water, particle count, elemental analysis, PQ index, FTIR oxidation	ferrography, micropitting debris review, filter debris analysis
Hydraulic systems	particle count, water, viscosity, acid number, FTIR, elemental analysis	patch microscopy, varnish potential, filter debris, servo-valve deposit analysis

large fan bearings
crusher bearings
slow-speed heavily loaded bearings
critical motor bearings with repeated failures

Grease-analysis tests:

consistency
oil separation
FTIR oxidation
wear metals
contamination
water
microscopy
thickener condition
ferrous debris
comparison to new grease reference

8.3 Sampling-point design

Khash should classify sample points as:

Primary diagnostic point: live-zone, turbulent, representative sample before filtration
Secondary cleanliness point: downstream of filters to check filtration performance
Reservoir point: used only for bulk fluid condition, not wear diagnosis
Drain sample: useful for changeout or inspection, not ideal for routine trending
Portable sampling point: used only where fixed hardware is impractical

Sampling procedures should define:

machine operating state
flush volume
bottle type
sample port cleaning
sampling sequence
labeling
required PPE
sample frequency
alarm response
resampling criteria
contamination-avoidance steps

8.4 Sampling frequency

A starting model:

Criticality	Asset examples	Frequency
A-class	kiln main gearbox, mill main gearbox, roller press hydraulics, critical fans, kiln support systems	monthly or biweekly if unstable
B-class	crusher gearboxes, major conveyors, compressors, separator drives	monthly to quarterly
C-class	small reducers, minor packer drives, noncritical conveyors	semiannual, annual, or exception-based
Commissioning / rebuild	all critical assets after overhaul or oil change	baseline sample, then follow-up after early operation
Abnormal condition	overheating, water ingress, filter bypass, noise, vibration, high particle count	immediate confirmation sample

9. Precision lubrication task engineering

Khash should convert every lubrication PM from vague instruction into a controlled technical procedure.

9.1 Bad PM language to eliminate

“Grease bearings as required.”
“Check oil.”
“Top up if low.”
“Lubricate conveyor.”
“Inspect gearbox.”
“Change oil annually.”
“Use standard grease.”
“Lubricate kiln gear.”

These are not auditable, not repeatable, and not aligned with ICML 55 discipline.

9.2 Required structure for a grease task

Each grease task should define:

asset ID
lubrication point ID
component type

9.5 Required structure for an open-gear lubrication task

Each open-gear task should define:

lubricant product
application method
spray duration
spray interval
nozzle pressure
air pressure if applicable
lubricant temperature if heated
spray pattern acceptance
tooth coverage acceptance
gear inspection location
cleaning requirement
pinion/girth alignment observation
lubricant consumption target

immediate stop criteria
corrective work-order trigger

10. Cement-specific model procedure: rotary kiln open-gear lubrication

Purpose

Maintain adequate lubricant film on the kiln girth gear and pinion to prevent adhesive wear, pitting, scoring, root buildup, edge loading, and excessive flank temperature.

Daily operator inspection

Observe open-gear spray-system status.
Confirm lubricant supply level.
Check spray-system alarm panel.
Look for abnormal overspray, dry teeth, heavy buildup, or uneven coverage.
Check pinion and gear guard area for leaks or contamination.
Record abnormal gear noise.
Check kiln drive temperature and vibration indicators.

Weekly lubrication-technician task

Verify spray nozzle condition.
Confirm spray pattern across full face width.
Check that lubricant is applied before mesh contact.
Inspect tooth flanks through safe access point.
Check for dry flanks, scoring, pitting, root buildup, and abrasive paste.
Confirm drum heater or lubricant temperature control if used.
Check compressed-air quality if air-assisted spraying is used.
Record lubricant consumption.
Clean overspray according to approved procedure.

Monthly reliability inspection

Perform gear contact-pattern review.
Compare pinion and gear temperatures.
Review vibration trend.
Review lubricant consumption trend.
Inspect for alignment-related edge loading.
Review spray-system downtime.
Verify no unauthorized lubricant substitution occurred.
Trigger RCA if abnormal wear, high temperature, high vibration, or repeated spray failure is observed.

Corrective action triggers

Any dry tooth flank
lubricant not reaching full face width
root buildup causing tooth-root packing
excessive lubricant throw-off
abnormal gear noise
rising pinion temperature
visible scoring
pitting progression
spray nozzle blockage
spray timing failure
unplanned lubricant change
edge loading
high vibration at kiln drive

11. Cement-specific model procedure: mill main gearbox lubrication

Purpose

Control wear, contamination, oxidation, and thermal degradation in a critical mill gearbox.

Daily operator inspection

Check oil level.
Check oil temperature.
Check gearbox vibration indication.
Check filter differential pressure.
Inspect for leaks.
Inspect breather condition.
Observe oil color through sight glass.
Listen for abnormal noise.
Check cooler performance if applicable.
Record abnormal readings.

Weekly lube-technician task

Inspect desiccant breather.
Check offline filtration operation.
Check filter-cart connections.
Check magnetic plug or magnetic debris collector where installed.
Verify no unfiltered top-up occurred.
Check top-up volume trend.
Drain low-point water if water-detection hardware indicates water.
Inspect oil sample port condition.

Monthly oil-analysis task

Draw sample from live-zone sample port under operating conditions.
Test viscosity, acid number, water, ISO particle count, elemental analysis, PQ index, ferrous debris, and FTIR oxidation.
Compare to target cleanliness and asset-specific trend.
Issue corrective work order if water, particle count, viscosity, oxidation, or wear debris exceeds limits.

Corrective actions

High particle count: inspect breather, seals, fill practices, filtration, and recent maintenance contamination.
High water: inspect cooler, seals, washdown, condensation, and storage-transfer practices.
High iron/PQ: inspect gear mesh, bearings, alignment, overload, oil film adequacy, and lubricant viscosity.
Viscosity decrease: check wrong oil addition, fuel/solvent contamination, thermal cracking, or shear.
Viscosity increase: check oxidation, soot/dust contamination, wrong oil addition, or water emulsion.
High oxidation: review temperature, oil age, air entrainment, and oil cooler performance.

12. Lubrication storage and handling design

Cement plants often lose lubrication control before lubricant reaches the machine. Khash should design storage and handling as a contamination-control system.

12.1 Main lube room

The main lube room should include:

enclosed, dust-controlled space
bunded storage
sealed bulk tanks
desiccant breathers on tanks
filter loops on bulk tanks
dedicated dispensing lines
color-coded and shape-coded lubricant identification
lubricant receiving inspection area
quarantine area for nonconforming lubricants
used-oil segregation
spill kits
transfer-container storage
grease-gun storage cabinet
FIFO control
shelf-life control
lubricant SDS access
sample bottle storage
filter-cart storage
cleanliness audit checklist

12.2 Satellite lube cabinets

Because cement plants are physically large, Khash should create satellite lube cabinets near:

quarry maintenance shop
crusher area
raw mill
kiln area
cement mill
packing plant
utilities

Each satellite cabinet should contain only approved lubricants and tools for that area. It should be sealed against dust and audited monthly.

12.3 Lubricant receiving inspection

Every lubricant delivery should be checked for:

product name
batch number
container condition
seal integrity
certificate of analysis where required
viscosity grade
contamination evidence
delivery cleanliness
correct labeling
approved product list match
storage location assignment

No lubricant should enter the plant uncontrolled because unauthorized substitutions are a major source of lubrication failure.

13. CMMS, lubrication software, and route governance

Noria’s LPD implementation phase includes turning the design into a working reality through team training and lubrication-route design in lubrication-management software. (Noria Corporation) Khash should use the CMMS/EAM for work control and a lubrication-management platform for lubrication detail.

Required data structure

Each lubrication point should have:

plant area
asset ID
component ID
lubrication point ID
lubricant code
application method
quantity
frequency
procedure
safety requirements
inspection criteria
route assignment
technician skill requirement
sample point ID
contamination target
criticality class
abnormality codes
corrective action triggers

Route design principles

Group tasks by area and access requirement.
Separate running and shutdown tasks.
Separate high-temperature kiln tasks from general routes.
Separate clean hydraulic sampling from dirty grease routes.
Avoid assigning too many small tasks to one route without quality checks.
Use QR/barcode confirmation for critical points.
Require abnormality capture with photo where useful.
Integrate failed route findings into corrective work orders.
Audit route quality, not only route completion.

CMMS integration

The CMMS should contain:

engineered PMs
corrective work orders
lubrication backlog
lube-related failure codes
oil-analysis work requests
hardware modification work orders
RCA triggers
shutdown lubrication work packages
route compliance reports
lube-room audit tasks
filter-cart PMs
automatic lubrication system PMs

14. Training and competency program

ICML 55 requires lubrication-management systems to be supported by competent personnel. Khash should build a cement-specific competency matrix.

Role	Competency focus
Plant manager	program sponsorship, reliability economics, KPI review
Maintenance manager	execution governance, backlog, compliance, contractor control
Reliability engineer	oil analysis, RCA, contamination control, asset criticality
Planner	route scheduling, shutdown lubrication work, PM optimization

Kiln crew	open-gear inspection, support roller checks, thermal abnormality reporting
Mill crew	gearbox inspection, hydraulic cleanliness, fan and separator lubrication
Quarry maintenance	mobile lubrication, dust control, automatic greasing systems
Operators	daily visual checks, leak reporting, abnormal noise/temperature reporting
Storeroom staff	lubricant receipt, storage, FIFO, product control
EHS	oil spills, waste oil, fire risk, coal mill lubrication safety
Contractors	plant lubrication standards, approved products, task discipline

Training should include:

lubrication fundamentals
contamination control
lubricant identification
grease-gun calibration
calculated greasing
ultrasound-assisted greasing
oil sampling
open-gear inspection
filter-cart operation
desiccant breather management
oil-analysis interpretation
hydraulic cleanliness
lube-room management
spill and waste handling
lubrication RCA
CMMS/lubrication software use

15. Root cause analysis and failure elimination

Khash should define lubrication-specific RCA triggers.

15.1 Mandatory RCA events

kiln main gearbox abnormal wear
kiln open-gear scoring or pitting
support roller bearing failure
mill gearbox failure
roller press bearing failure
repeated crusher bearing failure
hydraulic pump or servo-valve failure
repeated fan bearing failure
oil-analysis red alarm on critical asset
water contamination above critical limit
repeated high particle count
lubricant cross-contamination
unapproved lubricant substitution
automatic lubrication system failure causing asset damage
filter collapse or bypass event
open-gear spray-system failure
major lubricant leak or spill
repeated motor bearing failure after greasing

15.2 Cement lubrication failure taxonomy

RCA categories should include:

wrong lubricant
wrong viscosity
wrong grease type
wrong open-gear lubricant
wrong quantity
wrong frequency
grease incompatibility
oil cross-contamination
dust ingress
water ingress
poor breathers
damaged seals
poor transfer practices
poor storage practices
no filtration
poor sampling
poor oil-analysis interpretation
blocked grease line
failed injector
spray nozzle blockage
spray pattern error
overgreasing
undergreasing
thermal degradation
oxidation
abrasive wear
misalignment
overload
vibration
poor installation
poor shutdown cleanliness
contractor error
procurement substitution
inadequate procedure
inadequate training

16. Environmental, waste, and energy management

A cement lubrication program should improve reliability and reduce environmental burden.

Khash should implement:

lubricant consumption tracking by area
leak tagging
leak repair backlog
oil disposal tracking
used-oil segregation
grease waste control
oil reclamation for large gearboxes where justified
filtration and dehydration before disposal decisions
spill kits and spill-response training
bunded lube storage
drain-pan discipline during shutdown work
open-gear overspray control
compressor condensate oil management
hydraulic leak reduction
lubricant consumption per ton of clinker or cement
energy impact analysis for large gearboxes and mill drives

Cement guidance notes that synthetic gear lubricants in larger geared drives may provide meaningful power-consumption savings, depending on the application. (Machinery Lubrication India) Khash should treat energy benefit as a documented engineering case, not a generic sales claim.

20. Cement-industry conclusion

For the cement industry, Khash should make the ICML 55 lubrication-management system practical, field-based, and contamination-centered. Cement plants fail lubrication programs when they focus only on lubricant brand selection or annual oil changes. The real value comes from disciplined control of dust exclusion, open-gear lubrication, kiln-drive reliability, mill gearbox cleanliness, hydraulic cleanliness, precision greasing, oil analysis, automatic lubrication verification, storage and handling, and RCA.

The highest-priority cement assets for early implementation are:

rotary kiln girth gear and pinion, kiln main gearbox, kiln support rollers, raw mill gearbox, cement mill gearbox, roller press bearings and hydraulics, clinker cooler drives, crusher bearings and gearboxes, critical fans, compressors, and quarry mobile equipment.
