Asphalt Mixing plant dust Feature : 

The production process of the asphalt mixing plant : mixing, drying and screening of raw materials. The processed stones and asphalt are loaded into the drum and heated, and the aggregate, lime powder and hot asphalt are mixed to form an asphalt concrete product. During this process, a large amount of smoke and dust will be produced. The temperature of the dust and smoke is as high as 120℃-220℃, the humidity is 5-15%, the dust concentration is below 30g/m³, and the dust diameter is between 10-15μm. Due to the dust characteristics of the asphalt mixing plant, the dust bag made of aramid is the most suitable filter material for the asphalt mixing plant. 


Aramid Filter Bags Feature : 

1.Continuous operating temperature is up to 200°C, instant service temperature is up to 250°C

2.Fire retardant performance is excellent 

3.Corrosion resistance and alkali resistance is good 

4.Excellent thermal stability, excellent abrasion resistance and flexural resistance 

5.Hydrolysis resistance is poor, frequent SOx and vapor in flue gas or dew point will  greatly reduce its service life.

6.High and stronger tensile strength and abrasion resistance keep our Conex filter long working life.
