The material buffering capacity between the grinding disc and the grinding roller is insufficient, and it is easy to produce vibration. During the trial production of vertical mills, due to mechanical requirements requiring 70 feed, the feed is too small, which is one of the reasons for the large vibration of the vertical mill in trial production.
