Ball Mill Gear Box Lubrication
Coal plants use a mill machine to finely pulverize coal before burning. These mills use large speed reducers between the motor drive and the mill and pumped or forced oil lubrication systems lubricate this equipment. Lubrication pump(s) may be driven from the reduction gear box or separately driven using electric motors.
Three screw pumps are commonly used to provide lubrication oil in ball mill gear box applications. The primary benefit that the 3-screw pump delivers in this application is its high resistance to contaminated fluids‚ as the highly abrasive fine pulverized coal will migrate into the gears and the lube oil reservoir.
