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.
Dec 26, 2017· Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.
Loading capacity of the grinding media has a major impact on the efficiency improvement of ball mill. If the loading capacity is too small, materials impacts and grinding will be small, while excessive load reduces feeding, grinding interaction will be increased. ...
