How to calculate the Roll Crusher Capacity using a Formula. The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time. The formula, for material weighing 100 lb per ft3, is:
