  • Market segment: Cement
  • Component/application: Sliding runners
  • Major market: Maintenance, repair & overhaul (MRO)
  • Product: MOLYKOTE® BR-2 Plus Multi-Purpose Grease

Operational parameters (LETS)

Customer’s critical requirements

  • Problem category: Wear/failure
  • Problem details: The grease was quickly oxidizing from constantly being heated to +130ºC and being exposed to coke dust. There was wear on the contacting plate. As a result, the kiln seal was failing, resulting in coke being emitted into the atmosphere.
  • Root-cause analysis: The previously used grease (with EP additives) didn’t withstand the higher temperatures or abrasive dust particles.
