In the present work, the effects of some key grinding parameters such as ball size (2040 mm), grinding time (1030 min), solids content (6580%), and also ore work index ( kWh/t) on the grinding of some copper sulphide ore were investigated. Product 80% passing size (d80) was defined as process response.

How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, paint and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball mill rotates, the balls bounce around while striking the enclosed material.
