Jun 24, 2020 Ball mill has insufficient processing capacity and easily throws stones. For some ball mills, the feed amount of the mill is far from the design capacity in actual operation. When the feeding amount exceeds a certain limit, ball mill will throw out unground stones at the outlet, and the amount of stones thrown out is large.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
