The cement industry presents very demanding lubrication requirements.  The experience and expertise of Blue Star’s field support in this market will help you address your most challenging operations.  Our high performance grease and industrial lubricant product line is specifically engineered to address the friction, corrosion, deterioration, extreme temperatures and contamination issues that exist in the most severe environments.


Crushing methods and sizing processes that deal with hard rock or abrasive sand and gravels require heavy duty equipment such as: 

  • Gyratory (cone) and jaw crushers
  • Ball mills & bowl mills
  • Rock belt conveyance
  • Dust collector conveyance

Critical lubrication points on the crushing machinery include thrust and main shaft bearings, bushings and gears.  These applications demand a high performance industrial lubricant designed to provide more than the minimum lube film thickness for optimum tribological performance. Blue Star utilizes base oils, performance enhancing additives and solid film lubricant technology to improve asset reliability.  


Grinding operations exist in many aspects of a cement mill;

  • Raw meal grinding for supply to blending operations,
  • Coal mill grinding to supply fuel for the clinker burning process and
  • Clinker grinding for production of the finished cement.

Whether your grinding machines are built with a standard gear and pinion design or you have Horomill compression grinding machines, Blue Star lubricants are engineered to provide superior protection against friction and wear.  With our combination of high performance technology and onsite service Blue Star is prepared to become a vital part of your efforts to reduce maintenance costs, increase uptime and extend equipment life.  

Application Blue Star® Lubricant Design Comments
Bearings Greases are engineered to provide lubricating films that support loading and minimize contaminant damage
Mill Drives Mill motor bearing and planetary gear lubricants formulated for long life and durability
Girth and Pinion Gears Thermally stable open gear lubricants that are designed to stay in place without building in gear roots or on the gear guards
Drive Shaft Couplings Greases are formulated with high base oil viscosity, extreme pressure additives and lubricating solids

Blending and Storage

Pre-blending, blending, kiln feed and storage operations of a cement plant involve physical movement of raw materials, clinker and cement.  The mechanical operations include air slides, weigh belts, drag chain and screw or belt conveyors, bucket chain elevators and their head and tail tractions.  All require grease and gear lubricants. Blue Star Lubrication Technology has both high performance and conventional lubricants to meet the needs of all these applications.

Clinker Burning

Clinker burning operations contain the heart of a cement manufacturing process, the rotary kiln. Some plants use the modern shorter and wider kiln.  Others utilize the conventional high length to diameter ratio kiln.  Either way, the massive size of these reactors places heavy loads on the lubrication points. Depending on the time of year or kiln location, elevated temperatures impact the effective lubricating oil film associated with supporting this massive load. Call Blue Star today to leverage our high performance lubricants and application knowledge to enhance the reliability of your clinker burning assets.
