The Working Principle of Medium Crushing Cone Crushers: A Comprehensive Insight

1. Introduction to Medium Crushing Cone Crushers

Medium crushing cone crushers play a significant role in the mineral processing and aggregate production sectors. Their proper functioning is essential for efficient and effective crushing operations.

2. Key Components and Their Functions

The main parts of a medium crushing cone crusher consist of a frame, a transmission device, a crushing cone (movable cone), a fixed cone, a mantle, a concave, and a lubrication and hydraulic system. The crushing cone is supported by a spherical bearing and is driven by an eccentric shaft sleeve. The rotation of the eccentric shaft sleeve within the crusher frame makes the crushing cone perform a gyratory motion.

3. The Crushing Process

When the crusher is in operation, the material to be crushed is fed into the crushing chamber via the feed opening. The crushing chamber is formed by the mantle on the crushing cone and the concave on the fixed cone. As the crushing cone rotates, the distance between the mantle and the concave varies continuously. When the crushing cone approaches the fixed cone, the material is squeezed and crushed between them. This compressive force is strong enough to break hard rocks.

The design of the crushing chamber enables a step-by-step reduction in the material size. The material first enters the upper part of the chamber for an initial crushing stage and then moves downward for further refinement until it reaches the desired size. The crushed material is then discharged from the bottom of the crusher.

4. The Role of the Hydraulic System

The hydraulic system in a medium crushing cone crusher is crucial. It is used to adjust the discharge opening size, which directly determines the final product size. By regulating the hydraulic pressure, operators can precisely set the gap between the mantle and the concave, achieving the desired particle size distribution of the crushed product. Moreover, the hydraulic system provides overload protection. If uncrushable objects enter the crushing chamber, it automatically adjusts to allow the crushing cone to move back, preventing damage to the crusher. Once the object is removed, the crusher can resume normal operation quickly.

5. The Importance of the Lubrication System

The lubrication system is also vital. It ensures that all moving parts, such as the eccentric shaft sleeve, the spherical bearing, and the gears in the transmission device, are well lubricated. Adequate lubrication reduces friction and wear, extends the service life of the equipment, and guarantees its stable and reliable operation.

6. Conclusion

In conclusion, medium crushing cone crushers operate based on the principle of the gyratory motion of the crushing cone and the interaction between the mantle and the concave. The combination of the hydraulic and lubrication systems enhances their functionality and reliability, making them highly efficient and widely used in various industries. Understanding their working principle is the key to optimizing their performance and achieving better crushing results.
