Ball mill - WikipediaIn 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.feed of ball mill,Effect of ball and feed particle size distribution on the milling .In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material. The experimental parameters that were kept constant in this investigation.

How can one select ball size in ball milling and how much.

If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls. There should be atleast 25% empty place in the milling jar after feeding balls and the material while high energy impact. There is no such thumb rule for powder to ball ratio.

Ball mills are usually operated at 75% of the critical speed. If the speed is slower, the balls roll in a cascading motion, whereas at higher speeds, the balls are lifted and impact back against the bed (free-fall motion). The feed product is fed continuously through the trunnion and is discharged through slots on the opposite side.
