The dust collector in the asphalt mixing plant requires the use of acid and alkali resistant dust removal bags, as asphalt will decompose and produce acidic substances at high temperatures, and the dust in the mixing plant contains acid and alkali components. If ordinary dust removal bags are used, it will cause corrosion and aging of the bags, thereby affecting the dust removal effect and service life.
Generally speaking, the dust removal filter bag materials used in asphalt mixing plants are PPS or PTFE, both of which have good acid and alkali resistance. The specific specifications and sizes are selected based on the dust collector model and processing capacity of the mixing plant, and need to be purchased according to the actual situation.
During use, it is necessary to regularly clean and replace the dust removal bag to avoid clogging, aging, and other issues that may affect the dust removal effect due to prolonged use. At the same time, attention needs to be paid to maintaining the dust collector equipment to ensure its normal operation.
