Ball Mill Operatingprinciples Components Uses

Ball Mill Operatingprinciples Components Uses

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill
