— 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.
