Introduction of Cone crusher :
Cone Crusher is widely used for secondary and fine crushing in the fields of mining, chemical industry, building materials, metallurgy and so on. It can crush materials in middle and high hardness such as ironstone, copper ore, limestone, quartz, granite, rock and so on. The standard type (PYB) is applied to secondary crushing; the medium type (PYZ) and the short-head(PYD)Cone crusherare applied to fine crushing.
Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness.Compare with jaw crusher,cone crusher is of stable structure, high efficiency,easy adjustment,economic operation,etc. The spring safety system of crusher acts as an overloading protection system that allows metal 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 separate to make sure reliable performance.
Working principle of Spring Cone crusher:
Cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency efficient than jaw crusher. The movable cone is supported by spherical bearing and fixed on an 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 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 adjusted.

Advantages of Cone crusher :
1)High-effiency: the moveable shaft will continuously rotate ,and the materials crushing and the discharging process will take place in turn along the working surface .

2)Convenient operation and maintenance: The machine adopts the secondary vibration isolation technology so that the basic vibration is slight ,which features the convenient operation and low cost.

3)High-quality: The final products feature even size, and cubic shape .And the flexible cone wears evenly relatively.

The adoption of dry oil and water, prevents the dust from entering the machine body .This two kinds of sealing ensures the cleaning of the lubrication boiled oil and extends the service life of the slide bearing, which ensures that the machine can obtain a smooth function.

The Countershaft Part of Spring Cone Crusher:

The cone crusher is made up of main frame part, countershaft part, eccentric part, movable cone part, bowl part, and lubrication part.

The countershaft is in the frame driving axle box. The front of the countershaft is holding-on with the pinion and the gear which is on the eccentric. The other side is connect with belt and motor by belt pulley.

The shaft bearing of cone crusher consists of rolling bearing and sliding bearing. Both of them have their own advantages. When the quality, assembly, and lubrication of the countershaft are all good enough, the work efficiency of rolling shaft will be great. And it will have a long service life, and also it will be convenient to maintain.

Note for Cone Crusher Maintenance:

1. the materials must be in the middle of the distributor, see diagram 14. it is not allowed to put the materials into the crushing chamber directly, because it will make the crusher overloaded and the liner plate will be abraded unevenly. Correct feeding conditions:

a. the materials are distributed equally to the crushing chamber.

b. The quantity of materials should not higher than the mortar.

2. the max feeding size should not equal to the feed opening, (the max feeding size=85% of the feed opening) otherwise, it will lead to:

a. the capacity is low

b. some spare parts will be damaged.

3. crusher is not allowed to start in overload condition in case of accident.

4. when stop the crusher, stop the feeder first. After the materials are all discharged out, stop the crusher.

5. the locking system and hydraulic station should be checked often to avoid problems.

The Factors to Enhance Crusher Capacity:

1. Proper selection of crushing chamber for material to be crushed.

2. A feed grading containing proper distribution of the particle sizes.

3. Controlled feed rate.

4. Proper feed distribution 360ºround the crushing chamber.

5. Discharge conveyor sized to carry maximum crusher capacity.

6. Properly sized scalping and closed circuit screens.

7. Automation controls.

8. Adequate crusher discharge area.
