Hydraulic cone crusher mainly consists of the main frame, transmission device, eccentric shaft, bowl- shaped bearing, crushing cone, crushing walls, concave, the adjustment device, adjust sets, hydraulic control system, hydraulic safety system,dust ring, sub-feed pan, adjust-parts for the hydraulic nesting stations mouth,etc..Via the motor drive circling, hydraulic cone crusher force the eccentric shaft in the axis line spinning to do a cyclical sport , when the crushing wall approach the surface and sometimes also from time to time leave the rolling surface of the acetabular wall,allowing materials in the crushing cavity to be milled and extruded.Insurance tank is not only to ensure the security,but also will be able to support the hydraulic sets and top taper, which can exclude the faulty objects in the crushing chamber and effectively realize the trouble shooting function without disassemblying. This individual design greatly reduces maintenance costs, while increasing the protection of the crusher.
