Download now of 36 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.

The test enables basic grinding power requirement in ball mills to be determined, from the feed 80% passing size (F80) to circuit 80% passing size (P80), using the classic Bond formula. The rod mill work index test requires 20 kg of material, which is crushed to mm (1/2) and tested in a standard Bond Rod mill.

Ball Mill Model The main structure of the ball mill is composed of three parts, namely the feed inlet, the cylinder part (work bin), and the discharge port. Figure 2(a) shows the structural model of a ball mill. In the mill cylinder part, there are lifters for turning over the particles. The quartz sand particles enter the cylinder through a
