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.
