The operating principle of the ball mill

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. Then, discharge of ground material performed ...

A fuzzy control method for ball mill system aased on …

Abstract: Aiming at the disadvantage of ball mill system control, a new control algorithm based on fuzzy logic control is proposed. Firstly, the dynamic characteristic of ball mill pulverizing is given. Secondly, the control method is introduced. For mill level control loop, by the fuzzy decision making, the mill fill level is represented by the out temperature and the differential pressure.
