Spring Cone crusher is suitable for crushing various kinds of ores and rocks of medium or above medium hardness. Cone crushers have many features like stable structure, high efficiency, easy adjustment, low operating cost and etc. The spring safety system 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 powder and engine oil separated to ensure reliable performance. The crushing chambers are depending upon the feeding size and the fineness of final products. 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:
Spring Cone crusher crushes materials through the working surface between the movable cone and fixed cone. The movable cone is supported by spherical bearing and fixed on a hanging erect shaft which is set in the eccentric sleeve, which 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 fabricated 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 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 are discharged from the discharging hole. The fixed cone can be ascended or descended by adjusting the width of discharging hole; consequently the output size is determined.
