Nov 19, 2015 · Most plants use some recycled pavement which is loaded, screened and fed to the drum mixer. Asphalt plant exhaust systems are designed to use an induced draft fan to maintain a constant drum vacuum pressure by drawing exhaust air from the mixing drum through an air cleaner (baghouse or wet scrubber).


mixing plant. The mixture from the drum mixer contains a higher moisture content than that from a standard dryer used with stackup plants. This higher moisture content combined with the addition of the asphalt cement during the heating and mixing cycle results in a low emission of dust particles from the exhaust stack.
