Roll Crushers - ScienceDirect
Capacity of Roll Crushers. The capacity Q of roll crushers is directly proportional to its width, W, diameter, D and speed of revolution of rolls . Under continuous and steady feeding conditions, the capacity is given by (6.5) Q = π 60 D W ω L ρ B = 188.5 D W ω L ρ B t / h. where D = diameter of roll (m) W = width of roll (m) ω = speed (rpm)
