During the use of asphalt mixing equipment, a large amount of dust pollution will be generated. To reduce the amount of dust generated, we can first start with the improvement of asphalt mixing equipment, and optimize the design accuracy of each sealing part of the machine through the design improvement of the whole machine. Do as much as possible It is completely sealed during the mixing process of the equipment, so that the dust can be controlled in the mixing equipment. In addition, it is necessary to pay attention to the details of optimizing the operation of the equipment, and pay attention to the control of dust spillage in each link.
