Synchronous Ball Mill Motor Ball mills are used in many industries to grind coarse material into a fine powder. A ball mill typically consists of an horizontal cylinder partly filled with steel balls that rotates on its axis, imparting a tumbling and cascading action to the balls. In cement manufacturing, clinker is fed into the mill and is ...

Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
