A greater size reduction ratio can be obtained in fine crushers than in coarse crushers 13. types of grinding grinding may be carried out either wet or dry. wet grinding is generally applicable only with low speed mills. the advantages of wet grinding are the power consumption is reduced by about 2030 per cent.

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines.
