Cone crusher is a relatively important equipment in the production line. It is gener y used in production lines where the crushing materials are relatively hard and the output is high. The general environment in the mine production line is harsh and some failures will inevitably occur. These failures not only affect the normal of the crusher, but also ly shorten the service life of the components and lubricants of the crusher, ly increase the consumption of spare parts and materials, and increase the labor intensity of maintenance and production. Therefore, correct handling of these faults can ensure stable operation of the cone crusher and improve production efficiency.

    First, the common failures and reasons analysis of cone crusher
    Cracking sound when breaking ore
    Main reason: The working mechanism of the cone crusher is composed of a crushing cone with a liner and an adjusting ring. A layer of zinc oy is cast between the cone of the crushing cone and its liner, and between the liner and the adjusting ring.
    At the same time, it is hung on the adjustment ring by a U-shaped screw through a hook on the lining plate to ensure a tight connection. During the operation of the crusher, when the crushing cone or the liner of the adjusting ring is loose, the cracking sound of the crushed ore will occur.

    2. The crusher often vibrates
    main reason:
    1) For spring cone breaking, when the spring tension of the crusher is not enough, the crusher will often vibrate.
    2) When the feeding of the crusher is uneven or excessive, it will often cause the crusher to vibrate.
    3) When there is too much fine ore in the feed of the crusher and it is wet, the ore discharge port of the crusher is sm , causing the ore discharge at the ore discharge port to be often blocked, which causes the crusher to vibrate frequently.

    3. Worn large and sm bevel gears, broken teeth
    main reason:
    1) The normal meshing conditions of the bevel gear are damaged
    2) Rigid connection transmission
    3) Crossing iron frequently or being bitten by a large block

    4. Poor quality of lubricating oil
    main reason:
    During the operation of the crusher, when the water seal and dustproof device is not tightly sealed, a large amount of dust will enter the lubricating oil in the body, which will rapidly deteriorate the oil quality of the lubricating oil, cause poor lubrication, and cause large and sm bevel gears. Accidents such as beating teeth, high-speed rotation of the moving cone, holding the shaft and grinding the bush, etc., also ly shortened the service life of the lubricant.

    5.The crusher has strong vibration, and the moving cone autobiography is fast.
    main reason:
    When the cone crushing motorized cone rotates at a high speed beyond the normal speed, the phenomenon of "flying" often occurs. After the “speeding” fault, the revolution of the moving cone was too high, which would cause the oil temperature of the lubricating oil to rise, but the oil pressure to decrease; the current of the motor increased.
    The temperature of the bush at the moving cone and the eccentric shaft also rises sharply; the splash of lubricating oil inside the machine is thrown around, and the lubrication condition is deteriorated; the water seal is broken, and water in the fuel tank. "Flying car" failure will cause the crusher to vibrate strongly, the main shaft to be hugged, and tile breaking.
