  • Dust distributor for asphalt mixing machine
    Patent number: 6196710
    Abstract: An apparatus for making asphalt paving material includes a dust collection and distribution system by which aggregate dust that is collected during the heating and drying of aggregate may be introduced into the mixing chamber and distributed over a substantial portion of the area of the mixing chamber. By distributing the aggregate dust over a broader area of the mixing chamber than has been previously known, the mixing effort required to achieve a thorough blending of the dust into the mixture is reduced, and the quality of the asphalt paving composition is improved.
