Fracture causes of Cone Crusher spindle

1. Oversupply
 
When the feeding material is too much, the broken cavity will be full, which will bring the crusher a great pressure, and finally make the cone break overload operation. For a long time, this will lead to the fracture of the main shaft of conical rupture.
 
2. Equipment aging
 
Conical break of the working environment is relatively bad, and in the work will withstand long-term mechanical impact. Long service life, equipment aging, spindle fatigue, damage, eventually leading to the main shaft fracture.
 
3, Doped metal impurity in broken material
 
In the process of ore transportation and collection, some metal materials from unknown sources, such as forklift bucket, may be mixed, and some metal impurities will appear during the use of the loader. In addition, the metal in the ore may also be caused by various damaged bearings, bolts, and hinged pin shafts. When these metal materials pass through the electromagnetic iron remover installed above the conveyor belt, due to the low adsorption capacity of the electromagnet, there are also manganese steel metal properties, which can not be discharged by the electromagnet. When these metal impurities are adulterated into the crushing material into the crushing chamber, the cone will break iron frequently, and the spindle and other components will be made. Frequent impact pressure eventually leads to fatigue, wear and fracture of the spindle.
 
4, Other parts damaged
 
Some enterprises pay less attention to the damage of parts. In the process of cone breaking, the broken parts such as drive shaft, transmission gear and eccentric sleeve can not be detected and stopped by the operator in time, resulting in these fragments entering the crusher. And into the meshing transmission bevel gear, the transmission gear damage or even collapse, thus increasing the spindle pressure, resulting in spindle fracture.
