In a feed milling plant, it has been observed that 80% of the feed passes through IS sieve 340 (3.25 mm opening) and 80% of the ground feed passes through IS sieve 40 (0.42 mm opening). The power requirement to crush the material with a feed rate of 3 ton h-1 is 6 kW. Power requirement to crush 2 ton h-1 of the same feed using the above system so that 80% of the ground feed pass through IS sieve 15 (opening 0.157 mm) is
