Feed A correct feed rate in the mill is important. if the feed rate is to high and the mill be filled up with material and trip on vibration, because the mill fan dont have the capacity to transport material out of the mill. If the feed rate is to low will the mill emptied out and trip on vibration, due to low grinding bed.

Design Method of Ball Mill by Sumitomo Chemical Co., Ltd ...
A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used.
MILLING CONTROL OPTIMISATION Mintek
stockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn. When the load becomes critically high, the feed needs to be cut in order to "grind the mill out". This dramatic change in mass flow and particle size is passed to the downstream processes, causing
An Effective Mixing for Lithium Ion Battery Slurries
groups [1] [2] [18] [12][25] analysed the mixing of lithium battery materials using ball mill mixers, and found that the solution viscosity would drop gradually and approached a stable, limiting value after a long periodof mixing. A ball mill mixer appears to be a suitable device for mixing electrode slurries, although its effectiveness is
The operating principle of the ball mill
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
