When some foreign matters that cannot be crushed go into the crushing chamber or the machine is overloaded due to some reasons, the spring protection system of Granite Stone Crusher Machine will increase the discharging mouth and the foreign matters will be discharged from the crushing chamber, thus realizing protection. If the foreign matters are stuck at the discharging mouth, the spring protection system will start the chamber cleaning system and continue to increase the discharging mouth, so that the foreign matters can be discharged from the crushing chamber of cone crusher. Under the function of the spring, the discharging mouth will be automatically reset and cone crusher will resume normal work. This series of cone crusher is divided into three types, namely coarse cone crusher, medium cone crusher and fine cone crusher and the customers can choose different type according specific needs.

Working Principle Of Cone Crusher

Cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficient than jaw crusher. The movable cone is supported by spherical bearing and fixed on a 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 driven 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 driven 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 ground into pieces; when the movable cone leaves, ground materials will be discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined adjusted.
