Started in 1980s, Zhengzhou Unique Industrial Equipment Co., Ltd (Unique Group) is already a famous manufacturer & developer of mining equipment like stone crushing & screening equipment and ore processing equipment in China. Our products scope mainly includes cone crusher, jaw crusher, impact crusher, sand making machine, vibrating screen, vibrating feeder, belt conveyor, stationary & mobile stone crushing plant, ball mill, magnetic separator and cement production line etc.
What is the reason for the overspeed of the cone crusher, and why?
1.There is a problem with the thermal balance of the cone crusher
During the operation of the cone crusher, the parts between each other will generate a lot of heat. Under normal circumstances, the heat will be converted and released through the heat exchanger to maintain heat balance. If there is a problem with the thermal balance, it can lead to some other failures and problems. With the continuous reduction of heat exchange efficiency, the heat balance cannot be maintained in a normal state, which will naturally lead to burns in many parts due to dry friction, causing the phenomenon of speeding.
2.The contact point of the cone crusher is less and the contact surface becomes smaller
If there are few contact points between the cone sleeve of the cone crusher and the main shaft, it will also lead to the situation of flying. The situation of flying cars is easy to appear on the time porosity of the crusher when the material is cut off. In fact, from the perspective, cone crusher manufacturers believe that this is a speeding situation caused by idling. If there is still such a situation after feeding, the speed of its autobiography will be out of control, resulting in the intensification of the speeding phenomenon. Because the taper sleeve is cracked during operation, the oil film will be destroyed in this way, and even the contact surface will gradually become smaller. In such a case, the temperature will soar due to dry friction, which will cause a speeding situation.
3. The load of cone crusher exceeds
If the cone sleeve of the cone crusher is affected by non-broken objects during operation, it will cause overload, which will cause the new filling to fall off, resulting in a smaller gap between the cone sleeve and the main shaft, resulting in the occurrence of overspeed condition.
