The Reasons Why There Is Too Much Vibration in the Operation of  Impact Crusher  
 

Main reasons:
1Bearing clearance exceeds the limit, or has been damaged. To solve such problems is generally replaced with new bearings;
2Overhaul assembly crusher the hammer installation errors. The hammer change the face of the U-turn is used to prevent the rotor weight loss of balance, hammer crusher must together change face U-turn, otherwise it will be a strong vibration in the operation;
3 spindle bending deformation. The solution is straightening serious needs to be replaced;
4 corresponding the two hammer weight difference of more than 5g. The workaround is to adjust the weight of the hammer, the corresponding difference between two groups hammer weight less than 5g
5Individual hammer may be jammed too tightly, not completely throw off the run. After stopping treatment approach is to hand (manual) rotation and observe the the hammer rotating flexible;
6 on the other parts of the weight in the rotor imbalance, then the need to carefully check and adjust the balance of the rotor;
I hope these can be helpful. . . .
