AMIT 135: Lesson 7 Ball Mills and Circuits Mining Mill

For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Installation Notes of Beneficiation Ball Millprm

The beneficiation ball mill generally applies horizontal mining operations. When the iron particle size is less than 25mm, the grinding operation can be carried out. When materials put into the ball mill, cylinder can be driven by motor and the steel ball can move to a certain height and fall down with the rotate of the cylinder.

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
