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
