Roll Crusher

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).
