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 ...
Jan 01, 2007 The energy required to crush rock material is proportional to the amount of new surface area that is created. Therefore, energy consumption increases with fines generation, and it can be estimated that 10 times more energy is spent in producing pond screenings than in producing 10SM sand, for the same weight.
