Cone crusher application

 

Cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry. Cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc. Type of the crushing cavity is decided by the application of the ores. Standard type is for PYZ (secondary crush); middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush.

 

 Cone crusher working principle

 

Cone crusher crushes materials by 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 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 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 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.

 

Cone Crusher Structure & Operation Principles:

 

Cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
During operation, the motor drives the eccentric shaft shell to turn around through ahorizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crushing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed.

The main features of Cone crusher:

 

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
