Standard Spring Cone Crusher

Cone crusher is generally used as secondary crusher for medium or above medium hardness, such as iron ore, copper ore, limestone, quartz, granite and sand stones ect., in metallurgical, construction, road building, chemical, silicate industries. Compare with jaw crusher, the spring safety system of cone crusher acts as an overloading protection system that allows hard materials(such as iron) to pass through the crushing chamber without damage to the machine. 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 PYB series cone crusher is widely applied to coarse crushing, PYZ for medium crushing and PYD for fine crushing.

Working Principle:
Spring Cone Crusher crushes materials by the working surface between the movable cone and fixed cone. The movable cone is supported by spherical bearing and fixed on hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. Cone crusher's movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, 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 grinded into pieces, when Cone crusher's movable cone leaves, grinded materials is 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.

Features:
1. Large crushing ratio and high working efficiency;
2. Perfect lubrication device guarantees machine reliability;
3. High quality wear-resistant parts reduce operating cost;
4. Long life and wide scope of application;
5. High capacity and less wear costs;
6. Stable running performance and easy operation.
