Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. 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 sure reliable performance.

Application:
1. Spring cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry.
2. Spring cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc.
3. Type of the crushing cavity is decided by the application of the ores.
(1)Standard type is for PYZ (secondary crush);
(2) Middle type is for PYD (tertiary crush);
(3) Short-head type is for primary and secondary crush.
Features:
1. High productivity; high quality
2.Less machine stop time
3.Easy maintenance and low cost
4.Unique crushing ability in primary, secondary and tertiary crushing
Working Principle:
Cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency 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 fimbriated 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 grinded into pieces, when the 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.
