A roll crusher capacity is a measure of the amount of weight per unit time that moves through a roll crusher during operation. The theoretical maximum capacity is calculated by the equation above, but typically there are a few inefficiencies in the system that cause the true number to be 10-30% less...Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.

They have a higher capacity than comparable single-roll crushers. For example, a two-roll crusher with 24-inch-long (61 cm) rolls crushing to ¾ inch (2 cm) has a capacity of 75 tons/h (68 metric tons/h), which is approximately 2.5 times the capacity of a single-roll crusher with the same roll width and topsize setting...The primary crusher is normally a gyratory or a jaw crusher, depending on the capacity. ...
