roll crusher pdf free

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 The required crushing power is a function of Bond work index, capacity and the reduction ratio
