Ball Mill: Operating principles, components, Uses

05/07/2022 · 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.

by the rolling elements. The over-rolling creates indentations in the raceways († fig. 1). Hard particles may cause inden - tations with sharp edges. When the area around the indentation is then subject to c yclic stress due to normal over-rolling by the rolling elements, surface fatigue is initi - ated and the metal will start to break away

Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the
