Energy requirements of size reduction of some selected ...

measure of the efficiency of the milling operation is based on energy required to create new surfaces. Size reduction is one of the least energy-efficient of all the unit operation and the cost of power is a major expense in crushing and grinding, so the factors that control this cost are important (McCabe et al., 2005). Energy is the prime mover of any economy and engine of growth around ...
