In a vertical shaft impact crusher, the aggregate feed is introduced into a shoe or pump spinning on a vertical axis. The aggregate feed is thrown centrifugalLY against a series of anvils, pockets of aggregate particles (i.e., autogenous), or a combination thereof. Vertical shaft impact crushers produce a small reduction ratio and arc often used for […]

The spindle of the cone crusher gyrates in an erratic pattern. When the cone crusher is turned on, the spindle pushes rock against a hopper. And then, the rocks will be broken up by the surface force. The rotor of the vertical shaft impactor works at a high speed, and the rocks will be crushed into small pieces by the velocity.
