### Roll Crusher - An Overview | ScienceDirect Topics

the capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).,crusher efficiency calculations - 911 metallurgist,considering a 30-in. diameter roll crusher the maximum size particle that can be nipped with the roll crusher set at 1 in. according to this equation is f = 0.085(15) + 1.0 = 2.28 in. <3½ in. feed. it will take larger than a 40-in. diameter roll crusher.
