Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...

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.

The material is added to the mill compartment, where it is exposed to the rotating balls. The forceful rotation of the balls grinds the material into a powder-like medium coarse. Ball mills are commonly used for grinding materials like ore, ceramics, and paint. Another difference between bead mills and ball mills lies in their construction.
