Control Philosophy For A Ball Mill

Ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills dry basis is typically 75 vol.- ore and 25 steel. the ball mill is operated in closed circuit with a particle-size measurement device and size.

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.
