Coal pulverizer grinding wheel

BEARING TYPE:

Tapered roller bearings, HH249910/HH249949 & EE350750/EE350351

CONDITIONS:

Coal dust caused bearing seizure, resulting in the dust being ignited. Bearing life 9 months.

RESULTS:

Used in addition to conventional lubrication, MicroPoly has kept contaminants out of the bearings. Life of the oil bath has increased twofold and is now changed out every 6 months. Bearing life has been extended to 10 years. Maintenance related downtime has been substantially reduced, with annual cost savings of $250,000.
