The energy required to crush rocks is proportional to the amount of new surface area that is created; hence, a very important percentage of the energy consumed to produce construction aggregates is spent in producing non-commercial fines. Data gathered during visits to quarries, an extensive survey and laboratory experiments are used to explore the role of mineralogy …
The generation of fines increases when shear is imposed during crushing. Aggregates produced in current crushing operations show the effects of multiple loading conditions and fracture modes.
In addition, it has motivated studies to reduce energy consumption, to attain optimal crusher design and operation, and to minimize waste. Aggregate manufacturing typically starts by blasting rock masses and is followed by a series of crushing stages. Comminution in typical hard rock quarries is sketched in Fig. 1 .
