Ball Mill Working Principle. In the case of a 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 from near the top of the shell
