1.The role of symons Cone Crusher main shaft
a. The symons Cone Crusher main shaft twists the symons main shaft to realize the change of the crushing wall and the mortar wall to achieve the purpose of crushing materials.
b. The lubricating oil can flow into the working surface of the bowl-shaped tile after passing through the broken body through the oil hole at the bottom of the main shaft to achieve the purpose of lubrication.
2. Precautions for the use of the symons Cone Crusher main shaft
a. Ensure that the cone head is tightened and not loosened every time the symons series mantle is installed, otherwise the head nut will be damaged.
b. After the symons crusher is hoisted out of the crushing part, the surface of the main shaft needs to be treated when it is loaded again, and you need make sure that there is no blank.
c. The surface of the symons cone crusher main shaft can be simply treated if the eccentric bushing of the crushing shaft is burnt.
3. Selection of the material of the symons Cone Crusher Main Shaft
a. For Preventing the occurrence of excessive iron, it is inevitable that some foreign matter will be mixed in the transportation of the stone before entering the cone crusher. In addition, it is non-magnetic and cannot be discharged through the iron remover. And the size is usually large and cannot be smooth through the stone crusher. These objects cannot be crushed. In the long term, it will cause the main shaft to wear out, and cause the cone crusher to overload operation, even the whole machine will get stuck.
b. Adjust the lubricating oil temperature. The oil inlet temperature should be around 38℃ under normal conditions if the spindle is to be used normally. And the temperature difference between the inlet and outlet should be within 3℃. If it exceeds, it means that there is overheating between the spindle and the sleeve. It will induce the spindle to break if the temperature goes down.
c. The choice of the symons Cone Crusher main shaft shaft material. It requires not only high stress performance, but also good toughness. Both are indispensable. Although some materials meet the requirements, they often lack toughness. Fracture events are prone to occur in China.
