Because of the existence of the disturbance force in the process of the cone crusher, the vibration of the cone is unavoidable. In order to make the crusher run well in the stable vibration condition, in addition to the standard parts of the crusher, the installation and maintenance of the crusher should be carried out according to the standard. For the vibration of the cone crusher, the following measures can be taken to solve the problem.
1, Put an end to the non broken material and bulk ore into the broken cavity Non crushing matter such as iron, steel and other pieces of old to Xiamen lump ore into the crushing chamber will make crushing machine load surge, sudden increase the amount of shock, not only the broken machine transient vibration increase, but also caused broken machine parts damaged, triggering the equipment accident. Such as broken shaft, fight tooth and so on. Therefore, in the crushing machine to the ore belt (especially in the broken equipment to the mine belt) must set up a good run in addition to the iron equipment, as well as continuous staff monitoring.
2, The body is looking for leveling and transmission parts After a long run of the cone crusher its body and foundation of the two concrete layer will become loose, the original installation to find the usual pad iron with vibration time effect and running away from the original position, so that the body is in a state of not level, its vibration will aggravate. The installation of the coupling between the horizontal transmission shaft and the motor shaft of the cone crusher must be installed in accordance with the standard to avoid the vibration caused by the non concentric. In addition, the rationality of the meshing clearance of gear will affect the vibration of the crusher, the top gap and the side gap to be assembled, can not be too large, can not be too small, otherwise it will cause vibration of the crusher.
3, An eccentric shaft sleeve and a bowl shaped supporting frame used to repair Due to the centroid of the eccentric shaft sleeve, nor on the axis of rotation, so it rotates in also produces inertia force, its value is equal to the inner hole of the eccentric sleeve of the inclusive quality in order to ensure the normal operation of, crushing cone shaft and the eccentric shaft sleeve inner hole must along the length of the contact; the gap between also of the eccentric shaft sleeve inside and outside surface with the main shaft and the rack bushing ensures the eccentric sleeve and relative sliding stability of the lubricating oil film is formed between the surface. Therefore, the wear of the eccentric shaft and its related parts seriously affect its normal operation. Through the bottom surface of the eccentric sleeve after welding turning processing, make the bottom recovery precision. The bowl shaped supporting frame is a support device of the crushing cone. It is very important to ensure the normal operation of the crusher. Due to the long-term operation of the cone crusher, the accuracy of the distribution table is reduced, and the surface of the table is loose and the vibration is generated. In order to solve this problem, it is necessary to repair the bowl shaped support frame and the frame of the frame. Repair at the original size standard for recovery of repair.
