Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...

3A: Ball Mill Fundamentals. Ball Mill Dynamics The basic objectives of ball milling is the size reduction of materials, called comminution. Size reduction in a ball mill is achieved primarily by the motion of the balls in the mill. By rotation, the mill elevates the ball charge and material and drops the load upon itself.. Comminution Mechanisms
