1.Ball Mill Design Power Calculation
Dec 12, 2016 The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific Ball mills (Fig 1.1) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as grinding media and driven by side or central drive. Cement ball mill is not only suitable for over-flow grinding, but also applicable for cyclic close-flow grinding together with powder collector. There are two ways of grinding: the dry way and the wet way. Features 1. Can work with grinding and drying equipment simultaneously. 2. Easy to adjust the fineness of grinding products. The Product size is adjustable in the range of 80-425 mesh. cement ball mill price is possible to produce 30-80 mesh coarse powder through special device in the machine if necessary. Cement ball mill is mainly consisting of feeding device, big gear, discharge device, cylinder, diaphragm plate, hollow shaft, liner, drive device and other components. Oleg D.
