Cement Grinding
Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding are generally found in cement plants for cement grinding.

How it Works: Crushers, Grinding Mills and Pulverizers
Ball mills use a tumbling process with stone or metal balls as the grinding materials to reduce the coarse material by means of impact and friction. Ball mills typically use water or other liquid and additives to help reduce friction and provide cooling during the grinding process.

Raw Material Drying-Grinding
In air swept ball mills, material is swept out of the mill by hot air /gas of significant velocity (5-6 m/s), through separator and coarse fraction is returned to the system for regrinding. In case of bucket elevator mills (gravity discharge mills), ground material is taken by conveyors to a separator where coarse was returned to the mill and

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories

How Coarse can Ball Mill Feed be
With regards to 3.5"- 4" media, typically for Ball mills of this size (16''), max size of ball used should be around the 50-60mm.
