Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.
