crushing, the size of the material is further reduced by wet grinding in rod mills or ball mills. The rod and ball mills are also in closed circuit with classification systems such as cyclones. An alternative to crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills

TS is fundamental to the crack-opening stages of crushing and BWI is an intrinsic material characteristic for the fine grinding process [23], [24]. These two parameters are inversely proportional to the energy efficiencies for crushing and grinding; higher TS and BWI require more energy, which results in lower breakage efficiencies. 2.
