Creative Ball Mill works on the principle of impact on the Feed material and also due to abrasion of one ball over the other and by the free fall of the balls. Due to the rotation of the mill, the mill charge is lifted on the inner periphery of the mill until a position of dynamic equilibrium reached ,then it falls down to toe of the mill ...

Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
