The main dust collector of the bag filter increases the air volume in the circulating airflow, and at the same time removes the dust particles in the airflow, and purifies the increased exhaust air volume and discharges it outside the vertical roller mill.
When the bag filter cannot perform the dust removal operation normally, then there will be a large amount of dust particles. The material accumulates in the air duct, causing blockage of the air duct. Therefore, it is necessary to stop the inspection of the bag filter in time to ensure the normal operation of the bag filter.
Insufficient power of the fan will result in insufficient air volume, and the material will flow normally in the air duct, which will also cause material accumulation.
