Jan 01, 2016 Capacity of Roll Crushers. The capacity Q of roll crushers is directly proportional to its width, W, diameter, D and speed of revolution of rolls . Under continuous and steady feeding conditions, the capacity is given by (6.5) Q = π 60 D W ω L ρ B = 188.5 D W ω L ρ B t / h. where D = diameter of roll (m) W = width of roll (m) ω = speed (rpm)

In this case, the performance of the crusher will be determined as the product of the mass of material emerging from the working chamber during the withdrawal of the moving jaw by the number of revolutions of the main shaft: Q =m⋅n . Thus, the theoretical capacity of the crusher will be determined by the formula of Levenson by the expression: B b

Jul 30, 2012 Roll Crusher Working Principle. Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum, phosphate
