Particles of average feed size 25 x 10-4 m are crushed to an average product size of 5 x 10-4 m at the rate of 15 tons per hour. At this rate the crusher consumes 32 kW of power of which 2 kW are required for running the mill empty. What would be the power consumption if 10 tons per hour of this product is further crushed 1x 10-4 m size in the same mill? Assume that Rittinger's law is applicable.
