(a) The power required to crush 100 ton/hr of a material is 179.8 kW, if 80% of the feed passes through a 51 mm screen and 80% of the product passes through a 3.2 mm screen. What is the work index of the material? (b) What will be the power required for the same feed at 100 ton/hr to be crushed to a product such that 80% is to pass through a 1.6 mm screen?
