Dust Control Solutions for the Asphalt Industry

Hot mix asphalt plants produce asphalt pavement mixtures, whose composition may include natural sand, crushed limestone, slag, gravel, oyster shells, weathered granite, crushed stone, quicklime, Portland cement, or other non-plastic minerals (collectively referred to as aggregates), depending on pavement grade requirements. After mixing, the hot mix pavement material is loaded into trucks and transported to the construction site. Transportation costs represent a significant expense factor, leading the asphalt industry to operate numerous plants situated near construction sites. Estimates indicate over 3,500 hot mix asphalt plants exist in the United States alone.

Typically located in urban or highly urbanized areas, hot mix asphalt plants generate dust issues that concern government agencies, the public, and plant operators. Air pollution control regulations are being developed worldwide, with many establishing specific provisions for asphalt plant operations. Today, all newly constructed asphalt plants must incorporate dedicated dust emission control measures. Furthermore, the growing demand for asphalt pavement mix necessitates greater focus on dust emission control than ever before.

Baghouse dust collectors remain the most widely used filtration solution in the industry for meeting emission control standards. They can be reverse-air, pulse-jet, or even vibrating screen types.

Huazhe specializes in manufacturing filter bags perfectly matched with major brands of asphalt mixing plant equipment, such as Ammann, Marini, Benninghoven, Nikko, Lintec, Astec, Parker, Tarmac, and KVM.
