  • Patent number: 5294062
    Abstract: Apparatus for processing asphalt material to be recycled by introducing used asphalt material from the field in relatively large pieces, as received from the field, into one end of a cage-like array of tubular breaker members while simultaneously heating the tubular breaker members from the other end of the cage-like array and rotating the cage-like array about a tilted central axis of rotation to tumble the material within the cage-like array and reduce the size of the pieces of material to a desired aggregate size within a mass of material moving toward the other end of the cage-like array, the tubular breaker members being spaced apart circumferentially such that only the desired aggregate-sized pieces in the mass of material pass radially out of the cage-like array for delivery and reuse, collecting and oxidizing pollutants emanating from the asphalt material being processed and, in an alternate embodiment, generating electrical power for use at the site of the apparatus.
