Ball Mill - Savree

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.

The Working Principle Of Ball Mill - Meetyou Carbide

May 22, 2019 The larger the ball to material ratio, the higher the grinding efficiency. But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties (Figure 8-2). The ball ratio is usually selected from 2:1 to 5:1.
