The working parts are two cutter heads, also called cones; one is fixed cone ( also called outer cone), the other one is movable cone ( also called inner cone. The outer cone is fixed, which is one part of frame; the movable cone is pluged freely in the eccentric bush, so the central axis between the fixed cone and the movable cone intersects and forms into a bevel. When rotating, the movable cone rotates along the inner suface of the fixed cone. The place that the movable cone pressedagainst the fixed cone becomes the crushing cavity, where the materials is pressed, impacted and bent by the movable cone. The place that the movable moves away from the fixed cone becomes the discharging open, where the crushed materials is discharged out under the role of gravity, and the materials are sent from the feed open.

Cone crusher includes spring cone crusher and hydraulic cone crusher according to its different machenicalstructure.  Generally, the cone crusher consists of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone,  hydraulic pressure station for adjusting discharge opening etc.
