ABSTRACT:
A closed, pressurized dust return system for introducing aggregate dust into a stream of liquid asphalt is provided. Aggregate dust is dispensed through a valve from a receiving chamber into a mixing housing. The aggregate dust enters the mixing housing at an intermediate location therein. The liquid asphalt is introduced into the mixing housing through a separate conduit at a location thereon above the point of entry of the aggregate dust. The liquid asphalt and the aggregate combine within the mixing housing to form a slurry composition. A heating jacket substantially surrounds the mixing housing and a system for preventing liquid asphalt from backing up into the receiving chamber is also provided. The dust return system is particularly useful in an asphalt plant using a baghouse.
