Five things to pay attention to when maintaining bag dust collectors

Compared with electrostatic dust collectors, bag dust collectors are easy to meet standards and have good working conditions, so they are widely purchased. However, since the main accessories of bag dust collectors, dust bags and dust frames, are vulnerable parts, special attention should be paid to maintenance during use. Make the bag dust collector achieve the best dust removal effect. Let us take you to explain the maintenance of bag dust collectors:

1. The mill equipped with water spray inside the mill should have good atomization. Stop the water a quarter of an hour before stopping the mill. Avoid the adverse effects of delayed water evaporation on the filter bag.

2. The wind pressure for cleaning the filter bag is maintained at more than 0.5MPa, requiring oil and water separation, and the air bag should be drained in time. Frequently check the opening and closing of the internal air path of the bag dust collector, control the cleaning wind, etc. Check the degree of blockage of the filter bag. If it is slightly blocked, it should be pulled out and dried in time, and patted to clear the blockage. The ventilation capacity is maintained normal to avoid the vicious cycle of continued operation due to blockage.

3. Regularly check the air leakage of the exhaust gas treatment system, implement plugging, and perform external insulation on the exhaust gas system out of the mill.

4. Start the cold mill in low temperature season, try to avoid excessive moisture in the material during the temperature rise period; pay attention to controlling the feeding speed; the circle flow mill can increase the amount of return powder to increase the wind temperature in the mill. Before stopping the mill, extend the stopping time as much as possible, stop the mixed material with high moisture content as early as possible, and extend the exhaust time in the mill after stopping the mill, and do a good job of mill body transfer.

5. The filling amount of the bin grinding body should be appropriate to avoid affecting the ventilation area of the hollow shaft. The grate slits should be cleaned in time, and materials such as iron slag are prohibited from entering the mill in the mixed material to avoid clogging the grate slits. The ventilation capacity in the mill should be maintained at a stable level; once there is a change, the exhaust fan can still be used to adjust and maintain the optimal ventilation volume in the mill.
