Cone crusher

Cone crusher is a kind of crushing machinery widely used in metallurgy, construction, road construction, chemistry and silicate industries. It's detailed introduction is as follows：

I. Definitions and classifications

Cone crusher, also known as cone crusher, is a kind of equipment that uses the rotation of the cone and the change of eccentricity to achieve material crushing.According to its working principle and structural characteristics, cone crushers can be divided into various types, including hydraulic cone crushers and spring cone crushers.Among them, the hydraulic cone crusher can be subdivided into multi-cylinder hydraulic cone crusher and horizontal bar hydraulic cone crusher.

II. Principle of operation

The working principle of the cone crusher is that the material enters the crushing chamber of the cone from above. Under the action of the rotation and eccentricity of the cone, the material is compressed, bent and cut to achieve the effect of crushing.The broken material is discharged from the discharge port, and the size of the finished particles can be controlled by adjusting the gap between the cone and the broken wall.

III. Structural components

Cone crusher mainly consists of frame, main shaft, fixed outer cone and liner, eccentric sleeve, movable inner cone and liner, transmission device, crushing chamber, adjustment device, lubrication system, insurance device and other parts. Among them, the cone is the core part of the crusher, which is composed of moving cone and static cone, the static cone is fixed on the frame, and the moving cone is driven by the transmission device to rotate. The crushing wall is the part that forms the crushing chamber with the cone, and the size of the crushing chamber can be changed by the adjusting device.

IV. Features and advantages

1. High production capacity: The cone crusher combines a higher speed with a stroke, which greatly improves the rated power and passing capacity.
2. Uniformity of product particle size: The lamination and crushing effect between the particles makes the particle size more uniform and the product shape more neat.
3. Good stability: It can be produced under a constant discharge port, avoiding changes in the discharge port caused by the hydraulic cylinder supporting the moving cone floating up and down during the production process.
4. Reduce downtime: The two-way iron release hydraulic cylinder allows the iron block to pass through the crushing chamber. The hydraulic cleaning of the crushing chamber has a large stroke and has nothing to do with the wear of the liner, reducing the workload required to remove clogged materials in the crushing chamber.
5. Easy to repair: All parts can be disassembled and repaired from the top or side, which is convenient for maintenance.

V. Areas of application

Cone crushers are widely used in many sectors such as mining, smelting, building materials, roads, railways, water conservancy and chemical industry, especially for medium and fine crushing of various ores and rocks.

VI. Operation and maintenance

1. Handling Precautions：
   • Before starting, you need to check whether all the screws and spring screws of the equipment are tight, and whether there is any debris around the crusher equipment.
   • Check the crushing chamber for materials or debris and clean the crushing chamber.
   • Check the tightness of the triangle belt of the belt conveyor and whether the lubricating oil in the bearing seat is appropriate.
   • When starting the motor, pay attention to the safety of surrounding personnel and take protective preparations.
   • It is forbidden to carry out any adjustment, inspection, cleaning and other work during the operation of the crusher.
2. Maintenance：
   • Always check the fixing bolts that fix the dust-proof sealing slip ring to prevent it from falling off.
   • It must be produced at full capacity, otherwise the product will be too coarse-grained.
   • Replace the lubricating oil frequently, keep it clean, and avoid accelerating the wear of gears, bowl-shaped tiles, bushings, etc.
   • Regularly check the fixing condition of the slip ring to prevent dust and ore from entering the equipment body.
   • Pay attention to the oil level and water pressure in the fuel tank to avoid mixing the oil with water.

In summary, cone crushers play an important role in many industries because of their high efficiency, stability, and easy maintenance.
