ball mill operation process

The operating principle of the ball mill

For efficient operation of ball mills necessary to observe the right balance between balls size and feed material size If the feed material contains many large lumps and grinding balls can’t crush them, it leads to a gradual accumulation them between the balls As a result, mill suspends own operation

Overview

Ball Mill: Operating principles, 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 size The large balls tend to break down the coarse

Variables in Ball Mill Operation | Paul O Abbe®

Ball milling is one of the few unit operation that improves with increasing mill diameter If acceptable results can be obtained with a 12” jar mil, then good result will certainly be obtained with a 72” diameter mill Of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change media size or mill speed A general rule of thumb
