Sealing Wind Pressure Failure

[gjsohcat]

The sealing of the ultrafine vertical mill is to prevent high-concentration dust in the mill from entering the ultrafine vertical mill cavity and to protect the ultrafine vertical mill bearings from damage. High pressure air is blown into the ultrafine vertical mill cavity through the sealing machine to form a positive pressure in the ultrafine vertical mill cavity to prevent The purpose of dust entry.

However, the working conditions in the mill are very complicated, and the dust concentration in the suspended state is very high. The following situations often occur during the production process:

The air pressure of the sealing fan is low or the filter screen and filter cloth of the sealing fan are blocked by dust, which causes the sealing air volume and air pressure to enter the grinding cavity to decrease;
