### Ball Mill Maintenance & Installation Procedure

Mills are made either right or left “hand”. There are two methods of identifying the “hand” of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill. If it rotates counter clockwise, it is a left hand mill.

### Ball mill Wikipedia

In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell. In doing so, the solid particles in between the balls and ground are reduced in size by impact.
