The influence of materials on vertical mill vibration and the treatment method: it is mainly reflected in the particle size, the wearability and the moisture. In the vertical grinding operation process, to form a stable material layer, it is required that the grinding material has a suitable gradation, and more than 95% of the particle size is less than 3% of the roller diameter.
Vibration produced by the vertical mill not only damages the equipment, but also causes the instability of the table time and affects the output due to frequent roll-up and roll-off. The vibration of the vertical mill is related to many factors such as transmission, material layer, foreign matter, roll surface, grinding disc, particle size, pressure and so on.
