Cone crusher is suitable for crushing various kinds of ores and rocks of medium or above medium hardness, and cone crusher have many good quality features like stable structure, high efficiency, easy adjustment, and use economically, etc. The spring safety system of crusher works as an overloading protection system which allows metals to pass through the crushing chamber so as not to damage cone crusher. The safety system adopts dry oil and water as two kinds of sealed formation to make plaster powdeer and engine oil separated to make surereliable performance. Depending upon the feeding size and the fineness of crushed products, different crushing chambers are used. The standard type(PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing, and short head type is applied to fine crushing.
Working principle of Cone crusher:
Cone crusher crushes materials through 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 diacharging hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharging hole, consequantly the output size is determined.
