When the compound cone crusher working, the motor drives the eccentric sleeve to rotate via the belt, a big belt wheel, transmission shaft, bevel gear, bevel gear. Crushing cone axis swinging under the force of the eccentric sleeve, the surface of mantle sometimes close to and sometimes leave the concave surface. Material impact, extrusion, bending and crushing, in a circular crushing cavity of the fixed cone and moving cone. After repeated extrusion, impact and bending, material
crushing to the required size, being discharged from the outlet.
