Ball Mill - SlideShare

WORKING: The material to be grind is fed at angle of 60 degree into the crushing zone and the product is discharged at 30 degree. As the shell rotates the balls are lifted up on the rising side of the shell and they cascade down from near the top of the shell. The solid particles in between balls are ground and reduced in size by impact.
