Ball Mill Larger Or Smaller Balls Arsenic Ore

The larger pieces of ore keep the rods apart so that the grinding action is concentrated on the larger sizes and the smaller particles are not overground to the same extent as in a ball mill For these reasons the shell is made about 50 longer than that of a ball mill of the same diameter and still gives less undersize when grinding the same
