Results repeated for different sizes of the loading area point.Abstract. 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 and fracture mode in fines production during the crushing of single aggregates and aggregates within.
