other plants. A specific feature in running a ball mill is that the grinding mills are big power consumers, since grinding process is power-intensive. The electric power consumption for solid material grinding amounts up to about 20 % of the total power consumption for own needs of the plant or about 2 % of the total amount of power
Where, y is cumulative percent passing size d, d 50 is the 50% passing size, n is distribution constant, and k is a correction factor. The n values ranged from 0.84 to 1.84, and k values from 0.95 to 1.00. By using the Bond method of grindability, H. Ipek et al. [4] have observed that less specific energy input is required in separate grinding of ceramic raw materials than grinding them in

1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis-crete element method, we must first be able to repro-duce the balls’ motion in the ball mill using simula-tions. Kano et al.8) have made it clear that it is possible to reproduce the ball motion when the solid material is

The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al., 1976; Fuerstenau et al., 1999; Kotake et. al., 2004). The basic condition, which must be met while grinding the material in a mill is that
(t/h) = Total mill power (kW) x CSE (%) x Mill grinding rate of coarse material (t/kWh) (2) Production rate, mill power and CSE can be measured during a plant circuit survey. The mill grinding rate of coarse material is then calculated. At the circuit target P80 size, this is the mill grinding rate (of coarse material) through the size of interest.
