A rolling mill stand has upper and lower work rolls supported in chocks which include liner plates on their side faces for bearing against the side faces of the mill stand housing, with the side faces of the chocks being shaped so that the liner plates on both the upper and lower work roll chocks extend both above and below the pass line defined by the work rolls.

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 ...
