Asphalt mixing plant bag type dust collector is used in the production equipment of asphalt mixing plant. When the asphalt mixing plant is produced, it not only produces smoke, but also emits a lot of dust. Therefore, to increase the dust removal capacity, generally two levels of dust removal are used. If the two-stage dust collector used in the asphalt mixture mixing equipment adopts high dust removal efficiency, under the current situation in my country, it may affect the gradation of the mineral material, which may affect the quality of the asphalt mixture. The following is the analysis and suggestions for the working conditions of the dust collector of the asphalt mixing equipment.

There are three kinds of minerals used in the asphalt mixture, namely coarse aggregate (crushed stone with particle size above 4.75mm), fine aggregate (sand with particle size of 4.75mm-0.075mm) and filler (stone powder with particle size below 0.075mm) ), each material has certain requirements. It must also be clean, dry and free of impurities. At the same time, strict gradation design is required for the three aggregates of coarse, fine, and powder, so that the strength of the asphalt mixture can be the highest and meet the road driving requirements. If the various raw aggregates of the mixed asphalt mixture are very clean, there is no soil, or it is mechanical crushed stone, mechanical sand, the dust filtered by the dust collectors at all levels can be fully recycled, neither destroying the grade matching, nor Does not affect the strength of the mixture. In this case, the higher the efficiency of the dust collector at all levels, the better.

Pay attention to the wind speed, temperature, power supply, etc.
