Speed Roll Crusher Calculations . Design, Fabrication and Testing of a Double Roll Crusher. The capacity Q, of roll crushers is directly proportional to its width, W, diameter, D and the speed of revolution of rolls Under continuous and steady feeding conditions the capacity is given by the following [4], [5] Q = π 60 D W N L ρ = 1885 D W N L

ContactThe 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).

ContactJan 01 2016 0183 32 The springs are helical and pressure varies with the size of crusher and could be as high as 6 t/m about 8300 kPa In some roll crushers the rolls are individually driven The drive is either by gears or belt Both rolls usually rotate at the same speed but some crushers are designed such that one roll could rotate faster than the other...

ContactJan 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.
