Ball Mill Operation -Grinding Circuit Startup &

2016-2-1  Normal Ball Mill and Grinding Circuit Operation After the grinding circuit has been brought up to normal operating conditions, the operator must monitor the various process variables and alarms. Most of these variables are monitored in the mill control room, however, the operator is also required to sample and analyse process streams and read local indicators.

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
