Cone crusher is a mechanical device used to crush medium and high hardness ores or rocks. It achieves extrusion, crushing and screening of materials through eccentric rotation in the conical crushing chamber. The following is a detailed introduction of cone crusher:

1. Basic structure

Cone crusher mainly consists of the following parts:

Frame: the main structure supporting the entire equipment.

Crushing cone (moving cone): a conical component installed on the main shaft, which crushes materials through eccentric rotation.

Fixed cone (fixed cone): a conical component fixed on the frame, forming a crushing chamber with the crushing cone.

Main shaft: the core component that drives the crushing cone to rotate.

Eccentric sleeve: makes the main shaft produce eccentric rotation.

Hydraulic system: used to adjust the size of the discharge port and overload protection.

Transmission device: includes motor, pulley and gear to provide power.

2. Working principle

The working principle of cone crusher is based on eccentric rotation:

Material entry: the material enters the crushing chamber from the feed port.

Extrusion crushing: The crushing cone performs a swivel motion driven by the eccentric sleeve, forming an extrusion effect with the fixed cone to crush the material.

Multiple crushing: The material is subjected to multiple extrusions and impacts in the crushing chamber, and gradually crushed into the required particle size.

Discharge: The crushed material is discharged through the discharge port.

3. Main types

According to the structure and function, cone crushers can be divided into the following types:

Spring cone crusher: Overload protection is achieved by using a spring device, which is suitable for medium hardness materials.

Hydraulic cone crusher: The hydraulic system is used to adjust the discharge port and overload protection, with a high degree of automation, suitable for high hardness materials.

Compound cone crusher: Combining the advantages of spring and hydraulic systems, it is suitable for crushing a variety of materials.

4. Advantages

Efficient crushing: large crushing ratio and high production efficiency.

Uniform particle size: The crushed material has a uniform particle size and many cubic particles.

High degree of automation: The hydraulic cone crusher can achieve automatic adjustment and overload protection.

Stable operation: Reasonable structural design, smooth operation and low noise.

5. Application fields

Cone crushers are widely used in the following industries:

Mining industry: used for crushing iron ore, copper ore, gold ore, etc.

Construction industry: used for crushing limestone, granite, basalt, etc.

Metallurgy industry: used for crushing slag, refractory materials, etc.

Chemical industry: used for crushing chemical raw materials.

6. Precautions

Material hardness: select the appropriate crusher type according to the hardness of the material.

Discharge port adjustment: regularly check and adjust the size of the discharge port to ensure that the crushing particle size meets the requirements.

Lubrication and maintenance: regularly lubricate the main shaft, eccentric sleeve and other components to extend the life of the equipment.

Overload protection: ensure that the hydraulic system or spring device works normally to avoid equipment damage.

Summary

Cone crusher is an efficient and stable crushing equipment suitable for crushing medium and high hardness materials. Its core principle is to achieve extrusion crushing of materials through eccentric rotation motion, with the advantages of large crushing ratio, uniform particle size and high degree of automation. It is widely used in mining, construction, metallurgy and other industries.
