# roll crusher capacity calculation worksheet

density of roll crushers are low (0.15– 0.3) Substituting yields a capacity, Q = 1.430 t/hr. The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power

Sep 15, 2014 The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft. For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide
