Energy consumption in a jaw crusher. apr 15, the simulation results show that due to the high no-load power consumption of the jaw crusher, the optimal switching control of the jaw crushing process can achieve considerable energy saving and cost saving as compared to the variable load-based optimal.Energy consumption in crushing and grinding the energy input to size ore fragments is large. overall reduction, performed in a series of stages may be from an eighty percent feed size passing of 40 cm (15.8 inches) to a final product size of 270 to 325 mesh (.053 to .045 mm). a lot of energy is expended to accomplish this,.
Jun 23, this mode of breakage is similar to that occurring in a primary gyratory crusher where power rates (energy input per tonne of feed) are low (approximately 0.1 kwh/tonne). the procedure works quite well for this type of crusher but tends to understate power requirements in fine crushers where power rates are typically much higher (upwards from 0.Lbs/ton) and an explosive cost of $0.264/kg ($0.12/lb). electric energy cost is assumed to be $0.07 per kwh. table 1: energy and cost calculations by unit operation operation feed size product size work input energy cost cm cm kwh/ton $/ton explosives ∞ 40 .24 .087 primary crushing 40 10.2 .23 .016 secondary crushing 10.2 1.91 .61.
