ABSTRACT:. A High Energy Crushing Test (HECT) system was used to simulate the operational settings of a jaw crusher so that comparison of fracture toughness and specific comminution energy (the energy required to reduce a rock particle to a given size) could be performed. Since power consumption is a function of the crusher …
