During the operation of a cone crusher, various issues may arise. Due to prolonged operation, both major and minor problems can occur. One common issue is the fracture of the main shaft, which can significantly impact the normal functioning of the crusher. In the following section, we will explain some potential causes of main shaft fractures.
1) Because of its unique working feature for bearing mechanical impacting for a long time, the main shaft generates fatigue damage.
2) Feed more materials to cause overload operation.
3) There are some wasted metal mixed in the ore during excavation and transportation. When these materials pass through the electromagnet, because of the weak absorption ability of electromagnet and the special metal characteristic of materials which contained manganese steel, they are hard to be removed, so these materials mixed with ore and mud entering into crusher to cause frequently impact on main shaft. In this way, the main shaft generates fatigue damage, this is the main reason to cause breaking.
During the operation of the cone crusher, the operator should conduct routine testing and maintenance of the equipment and implement appropriate management measures. This will help mitigate damage caused by factors such as overload, excessive iron content, improper operation, and other adverse conditions, thereby reducing potential losses.
