Product Introduction

This product is a large-scale crushing machinery that utilizes the rotational motion of a crushing cone in the cone cavity of the shell to produce compression, splitting, and bending effects on materials, and coarsely crushes ores or rocks of various hardness. The upper end of the main shaft equipped with a crushing cone is supported in a liner in the middle of the crossbeam, and its lower end is placed in the eccentric hole of the shaft sleeve. When the shaft sleeve rotates, the crushing cone undergoes eccentric rotation around the center line of the machine, and its crushing action is continuous, so its work efficiency is higher than that of a jaw crusher. By the early 1970s, large rotary crushers could process 5000 tons of materials per hour, with a larger feed diameter of up to 2000 millimeters.

Advantages

The gyratory crusher is an efficient and high-capacity coarse crushing equipment, suitable for materials with various hardness, and has the following advantages:

1. Strong crushing ability: Designed with a large inclination angle and long crushing surface, it has high crushing ability and stable output.

2. Heavy duty structure: The ultra heavy frame, integral heavy spindle, and high-performance bearing design ensure the long service life of the crusher, allowing it to work without faults even in harsh environments.

3. Intelligent operation: The automatic control system not only controls and monitors various stages of crushing, but also simplifies operation, reduces maintenance and repair costs, increases startup time, and ensures the stability and high output of the crusher.

4. Easy maintenance: Easy to replace parts, even if the crossbeam must be removed, there is an auxiliary tool, hydraulic crossbeam separator. The movable conical locking nut with a cutting ring makes it easier to disassemble the movable conical liner. The automatic spindle position control system is easy to control product particle size and can also compensate for pad wear.

6. Efficient and energy-saving: The use of quartz material abrasives for mutual wear results in high crushing efficiency and low noise, saving about 50% energy compared to traditional crushers.

7. High degree of automation: It adopts a fully automated electronic control system and intelligent software, with functions of self diagnosis, self protection, and self adjustment, making maintenance simple and convenient.

8. Suitable for materials with multiple hardness levels: capable of crushing materials with different hardness levels, widely used for crushing medium to low hardness ores and non-metallic minerals.

9. Large output and good grinding effect: It has the characteristics of large output and good grinding effect, and is widely used in industries such as cement, building materials, metallurgy, chemical industry, power, coal, etc.

10. The investment cost is relatively high: due to the core components of the rotary crusher being made of high-strength materials and its complex structure, the investment cost is relatively high.

Working Principle 

The working principle of gyratory crusher is to use the rotational motion of the crushing cone inside the cone cavity of the shell to roughly crush ores or rocks of various hardness. The upper end of the spindle equipped with a crushing cone is supported in a liner in the middle of the crossbeam, and the lower end is placed in an eccentric hole of the shaft sleeve. When the shaft sleeve rotates, the crushing cone moves eccentrically around the centerline of the machine. The crushing cone can achieve material crushing and crushing at different speeds or through variable frequency speed regulation by an electric motor. The crushing action is continuous, so its working efficiency is higher than that of a jaw crusher.

In addition, the rotary crusher also has some auxiliary systems, such as lubrication system, hydraulic system, electrical system, etc., to ensure its normal operation and safety. Among them, the lubrication system is used to reduce bearing temperature and wear, the hydraulic system is used to adjust the size of the discharge port and achieve overload protection of the machine, and the electrical system is used to control the start, stop, and operation of the machine.

In practical use, users need to choose appropriate models and specifications of rotary crushers based on specific material characteristics and production requirements, and strictly follow operating procedures for use and maintenance to ensure long-term stable operation of the equipment and improve production efficiency.

Application Area

Gyratory crusher is a widely used crushing equipment, mainly used for coarse crushing of ores and rocks with various hardness. Its application areas include but are not limited to the following:

1. Mining industry: used for rough crushing of ores, providing qualified raw materials for subsequent beneficiation and smelting.

2. Construction industry: used for crushing building materials such as concrete and bricks, as well as recycling and reusing construction waste.

3. Road construction: used for crushing materials such as asphalt and cement, as well as stone crushing in road maintenance and repair.

4. Water conservancy and hydropower engineering: used for crushing rocks and concrete to build water conservancy facilities such as dams and embankments.

5. Environmental protection field: used for the crushing and reuse of solid waste, as well as the crushing and reduction treatment of hazardous waste.

In addition, the rotary crusher can also be applied in fields such as metallurgy, chemical industry, power, coal, etc. It should be noted that due to the unique structure and principle of the rotary crusher, its application field is limited to a certain extent. In practical use, users need to choose appropriate crusher models and specifications based on specific material characteristics and production requirements, and strictly follow operating procedures for use and maintenance.
