A roll crusher capacity is a measure of the amount of weight per unit time that moves through a roll crusher during operation. The theoretical maximum capacity is calculated by the equation above, but typically there are a few inefficiencies in the system that cause the true number to be 10-30% less. How to Calculate Roll Crusher Capacity?
