Mar 10 2020018332For a ball mill to work critical speed must be achieved Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill If a ball mill fails to reach critical speed the balls will remain stationary at the bottom where they have little or no impact on the material Ball Mills vs.
Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced.
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.
