Now, when the cement grinding ball mill is started, vibration values are around 14 mm/s, first 4 harmonics of the GM, and then for about half an hour they go up to 28 mm/s in horizontal direction while in the vertical and axial direction there is no such change.
In general, the ATOX50 vertical mill mainframe is 3500kw, because the material grindability of our factory is poor, and when it becomes worse, the ability of the vertical mill will be reduced and can only be forced to reduce the material operation, otherwise it will cause the vibration of the vertical mill and cause the operation instability.
• cement industry: Nghi Son, Vietnam, 1998,Guangzhou, China, 2005. Loesche developed the 4roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The development was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair
At present the vertical mill is the main equipment of cement raw material grinding. Vibration of vertical mill not only damages equipment, but also causes instability of roller lift and roller drop, which affects output. According to the author''s experience, the reason and characteristic of vertical mill vibration .
