GMSG GUIDELINE: DETERMINING THE BOND EFFICIENCY

Assume the rod mill Work Index of 9.5 applies from the actual rod mill feed sizeof 19,300 mµ (although some of this work might ideally be done by crushers to achieve a rod mill F80 of 16,000 m) to a rod µ mill (circuit) product size of 1,000 µm. W1 = 9.5 x [(10 / √ 1,000) (10 / √ 19,300)] = 2.32 kWh/t

Rod Mill an overview ScienceDirect Topics

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.

Effects of mill feed size and rod charges on grinding

The effect of reducing mill feed size on product fineness decreases with grinding time, while the effects of different composition of rod charges are very small. Smaller rod diameter, coarser mill feed size and shorter grinding time will increase the energy utilization. The energy consumption in batch grinding is described by the Bond method.
