Since the circular plate friction wear, changes affecting the backlash, in order to ensure proper meshing gears must be supplemented with the bottom cover gasket, the gasket should have a thickness equal to the amount of wear of the circular plate.

Bowl Bearings And Seals

Install bowl bearings, taken not to damage the wire rope slinger (hardwood and other objects can be supported on a wire between). Assembly, should be scraping the spherical bearing, crushing cone to ensure interoperability with the bowl in the outer sphere contacts should ensure that 0.35-0.5mm inner annular gap. Bowl around the bush with perfusion of the alloy nail bar fixed to the bowl bearing shelves, bowl-shaped bearing to prevent any rotation along the circumferential direction.Bowl-bearing frame and body with the key (pin) fixed, if found in the work bowl bearing frame and body there is a gap must be dealt with immediately.

Cone Crusher Working Note

    • Ore must be given in the middle of the disk allocation does not permit the ore directly into the crushing chamber.Because doing so easy to make crusher overload, the liner wear unevenly.
    • To the mine crusher maximum size allowed is equal to the mine mouth size (the maximum size of the ore block ≤ 85% to the mine mouth size) otherwise it will lead to:

The right to mine conditions

    • ore distribution plate uniformly dispersed in the crushing cavity.
    • ore can not be fed into the higher levels of rolling acetabular wall.

crusher some other parts damage

  • Not allowed to load starting crushers, load starting will cause an accident.
  • You must first stop to the mining machine and let the ore has been crushed.
  • Crusher work should always check the pressure and hydraulic locking system stops working, identify problems and timely treatment.

Crusher Output

Crusher output, and feeding methods, feeding fragmentation, fragmentation size Pai mine ore physical and mechanical properties, temperature and so on, vary widely, factory output was given under the conditions specified schematic throughput.

Replacement Of Rolling Acetabular Wall
