### 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. In these cases, need to reduce the size of crushed material or increase the size of the ...

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 ...
