Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness,and cone crusher is of stable structure, high efficiency, easy adjustment, and use economically, etc. The spring safety system of crusher acts as an overloading protection system that allows metals 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 separated to make surereliable performance. The type of crushing chamber depends upon the size of feeding and fineness of the crushed product. The standard type(PYB) 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. According to stave work need of Cone crusher,cone crusher is maily usely in the compressive strength not surpassing 300Mpa each kind of ore and rock to medium crush and in broken bits .this is a typical equipment of our country for crushing hard ore to medium crush and broken bits.it is widely applied.it has the charaterisrics of high reduction ratio, high output,,few powder lost, the product granularity even, strong compatibility of hard grain.

Principle of Cone Crusher:
Cone crusher crushes materials by the working surface between the movable cone and fixed cone. The movable cone of the cone crusher is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are drived by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is drived by motor through v-belts.The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve of cone crusher rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the diacharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequantly the output size is determined.
