Ball Mill Operating principles components Uses Ball Mills

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 sizeBall mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft x 8 ft with 75 HP to 30’ x 41’ and as much as 30 000 HP Larger ball mills are available with dual pinion or ring motor driv Our mills incorporate many of the qualities which have made the Marcy name famous since
