Estimate the power required, assuming that the crushing strength of the dolomite is 100MN/m2 and that crushing follows Rittinger's Law Problem No. 3 - A crusher was used to crush a material with a compressive strength of 22.5 MN/m2. The size of the feed was minus 50mm, plus 40mm and the power required was 13.0kW/(kg/s). The screen analysis of the product was: Estimate the power required, assuming that the crushing strength of the dolomite is 100MN/m2 and that crushing follows Rittinger's Law Problem No. 3 - A crusher was used to crush a material with a compressive strength of 22.5 MN/m2.
