Environmental protection drum asphalt plant strict environmental protection standards from asphalt aggregate storage, transportation, heating, mixing to unloading from the factory. The whole processing of drum mix asphalt plant achieve environmental protection operations, effectively control the production of harmful smoke, dust escape and high energy consumption The equipment provides an effective solution for asphalt mixture production enterprises facing pollution problems.

The dust removal system strictly guarantees environmental protection requirements. The coarse dust and fine powder are collected by using the combination of gravity dust removal and pulse line blowing bag dust removal. The coarse powder is sent to the hot bone lifter by the screw feeder, and the fine powder is recovered by the screw feeder at the bottom of the warehouse, and sent to the recycling powder warehouse by the star feeder, spiral feeder, and chain bucket elevator. The belt conveyor of drum mix asphalt plant is easy to generate dust when feeding. From the perspective of cost and environmental protection, a set of dust removal equipment should be shared with other powder weighing hoppers. Dust is also generated when powder is transported from the silo to the powder weighing hopper. A large amount of dust pollution will also be generated when the mixture is fed to the mixing drum.

When the bulk material is discharged to the bin, due to the drop and the pressure in the cabin, not only the problem of dust removal, but also the issue of pressure release in the cabin must be considered. Therefore, when selecting the drum asphalt plant, it must be considered. First, the filter element must have a good filtering effect. At the same time, dust quality control is closely related to the density, quality, particles and moving speed of the material. The polyester non-woven fabric is used to make the filter element, which has the characteristics of good air permeability, strong dust interception ability, high filtration accuracy, toughness and easy forming, so it is widely used at home and abroad. Dust collectors for asphalt drum mix plant are widely used. Most of the dust collectors for asphalt mixing plants are cement powder, coal ash powder, mineral powder and dust mixed with sand.
