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).

Jan 01, 2016Roll Crusher Geometry. Simplifying Equation (6.1), the radius of the roll is given by (6.2) R = L − d cos θ 2 ( cos θ − 1) Equation (6.2) indicates that to estimate the radius R of the roll, the nip angle is required. The nip angle on its part will depend on the coefficient of friction, μ, between the roll surface and the particle surface.
