The application of verticalrollermills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.

Rolling mill vibration is a worldwide problem, although it has been found that the mill structure defects are the main cause of vibration, but the inhibition measures are difficult to implement. So we discussed the rolling force parameters influence on rolling mill vibration and suppression measures from rolling technology in this article. The results show that the rolling force is increased ...
