• 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鈥檛 crush them, it leads to a gradual accumulation them between the balls. As a result, mill suspends own operation.
