Ball Mill and Grinding Circuit Preparation for StartUP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum.

Ball mills on the other hand, as far as process requirements are concerned, did not require variable speed. However, frequency converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting.

Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages.
