201621 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 ...

THE MODE OF BALL MILL OPERATION  energosteel
2020910 The mill operation modes are as follows: The ”cascade” – the rolling the grinding balls inside the mill drum. Mixed mode – the rolling the grinding balls when part of the grinding balls move in a circular trajectory with further fall. Waterfall – the grinding balls move along a circular trajectory and change it further under gravity.

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.
