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
Chat OnlineA 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
