  • Parameters Effecting Grinding Rate Of Ball Mill Crusher

    Ball mill is a hollow cylinder which rotates about its axis. The axis can be horizontal or be at some angle to the horizontal. The shell of ball mill can be made of strong steel and coated with refractory materials. Ball mill is partially filled with free moving media balls which can be made of steel, stainless steel, ceramic or rubber.Feb 08, 2017 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.
