  • Difference Between Sag Mill vs Ball Millmech4study

    Oct 12 2017 · Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place. 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 size.
