Abstract
Drum mix asphalt plant apparatus connected to a fiber filter dust collector for removing dust and other light particulate matter produced by operation of the drum mixer. Asphalt material is added to the drum mixer in a manner to minimize smoking of the asphalt material due to high temperature within the mixer, and the resulting dust and other fine particulate matter evolved from aggregate material within the drum mixer is withdrawn and collected in a fiber filter dust collector system such as a baghouse. The collected dust is returned to the drum mixer to be coated with asphalt material therein, so that the returned dust becomes admixed with the asphalt aggregate contents of the drum mixer.
