If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

As can be seen from Fig. 7, the contents inside the pulp lifter are always in contact with the grate till they get discharged into the trunnion, and hence flow-back becomes inevitable. As the mill speed increases, the greeter influence of centrifugal force causes discharge to occur later leading to carry-over of a fraction of the fluid (Fig. 8 ...

Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 25-75 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.

Peripheral Discharge Ball Mills. The several layers of balls lying on top of those next to the shell follow a similar cycle except that, due to relative difference in the two forces, their paths become more nearly vertical. The outer layers, spreading more than the inner layers, increase the area in the zone of the falling balls.
