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.
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables
Ball Mill and Grinding Circuit Preparation for Start-UP The following items must be checked before the equipment in the Grinding Circuit is started.
