Size reduction by crushing has a size limitation for the final products. If we require further reduction, say below 5-20 mm, we have to use the processes of grinding. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction, compression, shearing and attrition. The two main purposes for a grinding process are:

If the rock is abrasive and power is cheap then a ball mill would be preferred, if wear rates are not excessive and power is expensive then roller mills would be best. However, the high capital cost of the ball mill means that the abrasion rate must be quite high to justify the extra cost, and even for cement clinker there is a trend away from ...
