    Mar 19, 2017  In designing a closed-circuit crushing stage, the question of how much circulating load should be carried is a very important one. It not only has a direct bearing upon the capacity of the stage; it determines the amount of screening surface, and the elevating capacity necessary to handle the load in the circuit.
