Cone crusher is a kind of medium and fine crushing machine widely used in the market. It is specially designed for crushing hard stones. It has a good crushing effect on marble, river pebbles, granite, etc. It has the advantages of large crushing force, high efficiency, low maintenance cost, uniform product size, etc. It is suitable for medium and fine crushing of various ores and rocks.
Working principle of cone crusher:
When the cone crusher is working, the motor rotates through the belt pulley or coupling, the drive shaft of the cone crusher and the cone part of the cone crusher are forced by the eccentric sleeve to perform a swinging motion around a fixed point. Therefore, the crushing wall of the crushing cone is sometimes close to and sometimes away from the wall surface of the rolling socket fixed on the adjusting sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing cavity to realize the crushing of the ore. The motor drives the eccentric sleeve to rotate through the bevel gear, so that the crushing cone rotates and swings. When the moving cone leaves this section, the material that has been broken to the required particle size falls under its own gravity and is discharged from the bottom of the cone.
After the material is coarsely crushed by the jaw crusher, it is sent to the hopper of the cone crusher by the belt conveyor, falls on the distribution plate and enters the crushing chamber evenly (the crushing chamber is composed of a crushing wall and a mortar wall). In the crushing cavity, the material is subjected to the strong impact, extrusion and bending of the crushing cone at high speed and large stroke. The material is quickly crushed, slides down along the moving cone, passes through the parallel belt at the lower part of the crushing cavity, and then undergoes at least one crushing action. It ensures that the product particle size is evenly discharged from the crushing chamber.
The correct operation of the cone crusher:
1. The cone crusher should be started and stopped in order. The equipment should be started without load, and the material can be added only after the operation is stable. During production, it is necessary to pay attention to prohibiting overload operation. Before shutting down, the feeding should be stopped first, and the machine can only be shut down after all the materials in the standby machine are emptied.
2. The feeding of the cone crusher should be uniform during work. If the feeding is uneven, the production capacity will be reduced and the product size will be too large. At the same time, pay attention that the feeding material should not be too wet or too sticky, the fine particles should not be too much, and the particle size of the material should not be too large, otherwise it will cause stuffy traffic. Of course, if the material cannot be discharged smoothly, it will also cause the cone crusher to be stuffy. Adjust the discharge port size in time.
