In view of how to avoid cement blocking dust removal filter bag, the following points should be paid attention to:

1. Check the total moisture of grinding materials regularly, and pay close attention to whether the grinding materials, such as clinker, limestone and gypsum, are wet and damp; Ensure that the limestone, gypsum and other materials into the factory do not increase water due to rain leakage, control the grinding limestone water ≤1%, gypsum water ≤3%, strictly control the slag into the grinding water, do not put wet materials straight. Open drainage ditch in the wet slag stacking site of the combined storage tank to reduce the original moisture of wet slag as soon as possible. When the control index is specified, winter and summer can be different. In low temperature and rainy season, the ratio of mixed materials should be adjusted under the condition of quality permitting, so as to reduce the total moisture. For example, fly ash can be used to replace part of the slag.



2. Appropriately increase the ventilation in the mill to explore the optimal air volume range. The negative pressure of grinding head should be included in the required inspection items when operating the patrol inspection. The filling quantity of abrasive body in one bin should be appropriate to avoid affecting the ventilation area of the hollow shaft. In order to avoid blocking the grate, material such as iron slag mixed in the mixed material should be cleaned in time. To maintain the stability of the ventilation capacity in the mill at a good level; Once there is a change, the exhaust fan can still be used to adjust the optimal ventilation rate in the mill.



3. The wind pressure for dust removal and filter bag cleaning should be maintained above 0.5mpa, and the oil and water should be separated and the air bag should be discharged in time. Often check the inner air path of filter bag filter, control the air used for cleaning, etc. Check the clogging degree of dusting filter bag. Once the clogging is found, take it out and pat it to clear the clogging. Ensure that the ventilation capacity is maintained normally, and prevent the blockage from continuing to form a vicious circle.



4, the exhaust gas treatment system leakage inspection, the implementation of comprehensive plugging, grinding exhaust gas system necessary external insulation.




5. Make good production scheduling, and keep running as much as possible when the water content in grinding is too large, so as to reduce the frequency and time of stopping grinding; Stop grinding as far as possible to avoid the late night and morning, such as low temperature period, low temperature season especially pay attention to.



6. Start cold grinding in low-temperature season, and try to avoid excessive moisture of materials in the temperature-rising period into grinding; Pay attention to control feeding speed; Ring flow mill can increase the amount of back powder and increase the internal wind temperature. Before stopping grinding, the stopping time should be extended as much as possible, as early as possible for mixed materials with high moisture content, after stopping grinding, the exhaust time should be extended appropriately, and the grinding body should be rotated well.



7. The mill equipped with water spray inside the mill should ensure good atomization. Stop the water for a quarter of an hour before the grinding, to avoid the negative effect of moisture evaporation delay on dust filter bag.



The use of filter bag dust removal equipment for dust removal of cement mill can ensure the high efficiency of dust removal, but if not used properly, it will cause dust removal filter bag blockage, so when dust removal filter bag is used for cement mill, it should pay special attention not to let it be blocked.
