Reasons for the strong vibration of the grinder
It is common is feed mills that body of the hammer mil that has been overhauled and installed for the first time undergoes strong vibration during trial operation. There are several reasons for this situation:

(1) The hammer has installed incorrectly during the inspection and assembly. In order to prevent the weight of the rotor from losing balance when the hammers are used in reverse, all the hammers in the crusher must be changed and turned, otherwise strong vibrations will occur during operation.
(2) Corresponding to the difference between the weight of the sets of hammers exceeds 5 grams. The elimination method is to adjust the weight of the hammer so that the difference between the weight of the corresponding two groups is less than 5 grams.
(3) The individual hammers are stuck too tightly and are not thrown off during operation. It can be turned and observed by hand after stopping the machine, and find a way to make the hammer rotate flexibly.

(4) The weight of other parts on the rotor is unbalanced. At this time, you need to carefully check and adjust the balance.
(5) THe spindle is bent and deformed. The solution is to straighten or replace.
(6) The bearing clearance exceeds the limit or is damaged. Generally, the problem can be solved by replacing the new bearing.
(7) The bottom corner fixing nut is not fastened tightly or loosened during operation. The solution is to tighten.
