Why does the hammer crusher work with strong vibration?
This situation occurs mainly in the following aspects: 1. bearing clearance exceeds the limit or has been damaged. Generally, new bearings are used to solve such problems; 2., the hammer pieces are installed incorrectly when repairing and assembling the crusher.
Check whether the crusher parts are loose, after the power supply, first check the direction of the main shaft and arrow pointing in the same direction. Before starting, check whether the fasteners are loose or not and the degree of tightness of the belt. The first air around 1-2 minutes before work, Hebi China coal laboratory equipment crusher confirmed no abnormal sound, we can begin to work. In the initial job, try to work with fewer materials before putting them into formal production.
When the hammer is used to turn the face and turn back, to prevent the weight of the rotor from losing balance, all the hammers in the crusher must be turned together at the same time, otherwise there will be a strong vibration during the operation. 3., the main shaft will be bent and deformed. The solution is straightening, which needs to be replaced in severe cases; 4. corresponds to the weight difference between the two groups of hammers over 5G. The solution is to adjust the hammer weight, the corresponding two groups hammer weight difference of less than 5g; 5. individual hammer may card too tight, not completely off operation. The approach is adjusted by hand (artificial) rotation and observation, the hammer rotating flexible rotor; 6. other parts of the unbalanced weight, then need to carefully check and adjust the balance of the rotor; I hope to be able to help you
