Reasons for Spindle Fracture of Cone Crusher

Posted by yoyocrusher on August 2nd, 2017

sand making machine is an advanced high-power, large crushing ratio, high productivity hydraulic crusher. The machine is in the digestion and absorption of the country has 80 years of international advanced level of various types of cone crusher developed on the basis of. It is clearly different in design from the traditional cone crusher and concentrates on the main advantages of the various types of cone crushers so far known. Applicable to fine broken and ultra-fine broken hard rock, ore, slag, refractory and so on.

  Cone crusher operating environment is relatively poor, inevitably there will be some failures, today to tell you about the cone crusher spindle damage caused by three major reasons:
  
  
  1, the reasons: frequent iron,  Sand Making Machine  and body with the Department of fracture.
  

   Method: Install the iron protection device.
   
  2, the reasons: cone crusher continuous overload operation, in conjunction with the body of the spindle fracture.
  
   Method: cone crusher spindle fracture is usually expressed as support sleeve beating, this time should be reduced to feed.
   
  3, the reasons: bowl-shaped tile and body spherical friction is serious, so that the spindle too much into the spindle bushing, so that the operating gap is reduced, causing lubrication failure, the spindle in the tapered part of the fracture (lower).
  
   Method: The geometrical relationship between the cone, bowl-shaped tile and the spindle bushing is not correct, replace the bowl-shaped tile, surfacing and re-processing the body spherical or padded bowl-shaped shaft frame to compensate for the wear of the bowl-shaped tile and the body sphere.
