ball mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, and moist samples down to the finest particle size. the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding according to the need of customers, ball mills can realize both wet and dry production. ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter. feed particle size: less than production capacity: tons hoursep 01, 2019 where, is the power input to the mill, is the feed flow rate into the mill is the temperature of the mill feed, is the temperature of mill discharge, loss is the rate of energy loss to the environment fi is the mass fraction of mill feed solids in size class while pi is the mass fraction of mill product solids in size class
