calculation of crushing roll capacity

Design, Fabrication and Testing of a Double Roll Crusher
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.

Crusher Efficiency Calculations
Sep 15, 2014 It will take larger than a 40in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1½ in., then a roll crusher from the Roll Crusher capacity Table above could be used. If the output of this crushing process should have less material of the +1in. size, the larger crusher could be operated with a closed circuit.
