Sep 15, 2014 A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough

Apr 24, 2015 ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from
Feb 25, 2015 Capacity calculations • Capacity = D π x RPM x L x S x Bulk density • D is the Diameter of Rolls • L is the length of the rolls • S is the set of the crusher • Actual capacity is 12 –
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
Theoretical Capacity of Roll crusher = (0.0034 * N * D * W * S * ρ) tons/hr N = Number of revolutions of the rolls, RPM. D = Diameter of the roll, inches = 8
Feb 25, 2015 • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39. Capacity calculations • Capacity = D π x RPM x L x S x Bulk density • D is the Diameter of Rolls • L is the length of the rolls • S is the set of the crusher • Actual capacity
