The spring safety system of crusher acts as an overloading protection system that allows metal to pass through the crushing chamber so as not to damage the cone crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separate to make sure reliable performance. The type of crushing chamber depends upon size of feeding and fineness of crushed product. The standard type (SDY) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.

Features and advantages:
1.Rational structure, advanced crushing principle and technical data, reliable operation and low operation cost.
2.High crushing ratio, high efficiency and high productivity.
3.Reliable spring security system, which can provid effective overload protection.
4.Double-crushing cavity, which meets large range of size requirements.
5.Manual -operating hydraulic discharge opening makes your work easy and economic.
