Dominant Positions of Symons Cone Crusher produced by Shenyang Mining Heavy Equipment Limited Company:
1 The stone forms protection bottom during the production. The fuselage is durable in use without abrasion.
2 A few quick-wear parts are made of ultra hard and wear resistant material. It is convenient to change replacements because of small volume and light weight.
3 The air self-circulation system can reduce dust.
4 The chief axis bearing is circulated and lubricated in the thin oil station. There is reserve oil pump which provides oil for the main engine continuously.
5 Auto-control and emergency alarm can be achieved.
6 The top cap is upgraded by the hydro system to have convenient operation.

Principle of Operation:
When the Symons cone crusher works, the electric motor passes through the V-belt, large belt wheel, transmission shaft, small bevel gear and large bevel gear, and then takes the eccentric bushing to rotate. The crushing cone axis line rotates under the function of the eccentric bushing; the surface of the crushing wall closes to and takes away from the surface of the rolling mortar wall by turns. At the end the material is crushed to be the required size to discharge from the output after continuous lashing, extruding and bending in the ring crushing cavity which is made up with fixed cone and moving cone.
