3a. Give a general expression for estimating the power consumption in crushers and grinders and derive the three laws from this general expression. b2. It is found that the energy consumption required for size reduction of particles from a mean diameter of 15 cm to 5 cm is 10 hp.h/ton. Estimate the energy requirement to reduce the same particles from a diameter of 31 cm to 5 cm at a loading rate of about 10 tons/h assuming: 1) Kick's Law 2) Rittinger's Law 3) Bond's Equation
