A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Effect of the lower cutoff of the size distribution on the specific power consumption, (a) 5 vs. 10 mm for an AG mill, and (b) 1, 2 and 5 mm cutoffs for the rock size in a ball mill. Next we consider the ball mill (rock and ball) cases with smaller cutoffs.
Reductions in the range of 4-6 kwh/t cement are reported from India, depending upon the product type. In China, for 5000t/d cement production line using a ball mill with closed circuit system, power consumption index is reported to range between 38 ~ 42kWh/t (NDRC, 2008. p.48).
mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being widely used for raw material and coal grinding ...
