The abnormal sound of ultrafine vertical mill will produce great noise. In daily production, noise is inevitable, but too much noise will have adverse effects on the staff. Therefore, the following measures can be taken to reduce the noise:

Select Bearing With High Box Size

The vibration of the bearing during operation includes two aspects:

One is structure: the rolling body causes the small change of the axis position through the composite action, which causes the vibration;

The second is manufacturing: the geometrical errors of rolling body, inner and outer ring, cage and so on will cause vibration.

The load, speed, lubrication and working clearance will affect the vibration of the bearing to varying degrees. Therefore, when selecting the bearing, the bearing life conditions must be satisfied first, and the bearing with smaller size and higher box size shall be adopted as much as possible.
