Principle and structure of cone crusher

In the working process of the cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device. The moving cone rotates and swings under the forced movement of the eccentric shaft sleeve. The static cone is broken by multiple squeezing and impacts. When the moving cone leaves this section, the material that has been crushed to the required particle size there falls under its own gravity and is discharged from the bottom of the cone.

Working principle of cone crusher


Cone crusher is mainly composed of hydraulic system, sealing system and crushing cavity type system. The main components are frame, drive shaft, eccentric sleeve, spherical bearing, crushing cone, adjusting device, adjusting sleeve, spring and discharge opening.
 
        Hydraulic system: The machine has a hydraulic system to adjust the size of the crusher's discharge port, which can effectively ensure the operation of the equipment. When there is a foreign body in the crushing chamber, the hydraulic system can automatically retreat the moving cone. When the foreign body is discharged, the system automatically resets the retreated moving cone.

        Reliable seal The labyrinth seal device replaces the water seal used in the past to prevent dust and impurities from entering the body of the human body, thereby ensuring the cleanliness of the lubricating oil, extending the service life of the sliding bearing and thrust ball bearing, and making the machine run reliably ;

Crushing cavity type: The crushing cavity type refers to the geometric space formed between the moving cone and the fixed cone. The shape of the crushing cavity has a great influence on the performance of the whole machine. Crusher cavity type is the main technical index of hydraulic cone crusher crushing. The machine is designed with four specifications of cavity from coarse crushing to fine crushing. It has six possible combinations, which means that it can be adapted to the special requirements of users;
 
        Crusher main frame assembly: The main frame of the crusher is composed of an upper frame and a lower frame, which are connected by hydraulic cylinders, with wear-resistant liners and protective covers: the upper frame is a welded part, and the upper port is welded with wear-resistant The copper plate and the lower frame are integral steel castings.
 
Main shaft assembly: The main shaft and the lower frame of the main frame are assembled with a small interference fit on the cone surface. The main shaft has axial and radial lubricating holes.
