Hogg and Fuerstenau [] using an approximate model of the motion of the ball charge derived a simple equation relating mill power to mill dimensions, speed of rotation, and the ball filling this model, it was assumed that the charge consists of two distinct regions: a "static" region where particles do not move relative to the mill shell and a "shear" zone where particles flow ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batchoperated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.
