Dual roll crushers, how they function
Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls.
Roll Crusher - Mineral Processing & Metallurgy
Roll Crushers. It is generally considered that Roll Crushers are specially adapted for intermediate crushing, taking a product from rock- breakers with a maximum diameter of from ¾ inch to 1½ inches, and reducing it to a size passing through a screen of 12 or 16 meshes to the square inch. Finer crushing, however, is often carried out.

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).

Next, the two-toothed roll crusher was optimized based on the framework proposed by the Whiten model. The reasonable rolls gap and teeth length should be 75 mm and 23 mm, respectively. Further, a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter; it was later found to be >660 mm.

Equipment Sizing: Crusher or Grinding Mill
By referring to equipment manufacturer’s bulletin on crushers, Fig. 1, a crusher producing 80% passing 3/4″ requires a close side setting of approximately 5/8″. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. The 159 indicates a 548 crusher size with 1″ eccentric throw.
TECHNICAL NOTES 5 CRUSHERS - Mineral Tech
The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
