Design Fabrication and Testing of a Double Roll Crusher
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  . Thus the actual capacity Q = .356 t/hr 2.1.9 Crushing Power
