Section For Impact Ball Mill Plant. FOB Reference PriceGet Latest Price. The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore the purpose of grading steel balls is to meet the requirements of these two aspects.
Ball mills are used in many industries to grind coarse material into a finer powder. A ball mill typically consists of a horizontal cylinder partly filled with steel balls that rotates on its axis, imparting a tumbling and cascading action to the balls. In cement manufacture, clinker is fed into the mill and is crushed by the impact of the
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.
