mass flow in impact crusher

2008-8-1 · The mass flow into the crusher can be controlled in order to achieve a stable process. The principle means for controlling this mass flow is through use of a throttle. In Fig. 3, the open area through which the material can pass into the crusher is represented as the area inside the circle that is
