Abstract: An asphalt manufacturing assembly (10) is disclosed that includes a rotatable cylindrical dryer drum (11) having an opening (14) in the front (12) for receiving virgin asphalt aggregate and for permitting the exhaust of fumes and an opening (18) in the back (13) for discharging the heated aggregate and for permitting the introduction of air. A burner (41) adjacent the back (13) introduces a flame and heat into the dryer drum (11). A longitudinal air conduit (22) is formed by a stationary annular shroud (20) around the back portion of the dryer drum (11) that extends longitudinally beyond the dryer drum back end (13). The shroud (20) includes two controllable discharge openings (24,25). The assembly (10) further includes a separate rotatable cylindrical mixer drum (51) having a materials inlet (54) for receiving the aggregate discharged from the dryer drum (11), reclaimed asphalt pavement, liquid asphalt and fines and a discharge opening (58) for discharging asphalt.
Abstract: An apparatus for remediating soil contaminated with combustible pollutants comprising means for initially heating the contaminated soil to a temperature sufficient to vaporize contaminants present therein, means for feeding the contaminated soil to the initial heating means, means for reheating gases created by vaporizing the contaminants, means for introducing the gases to the reheating means, means for cooling the gases, means for removing particulate matter from the gases, and means for exhausting the gases to the atmosphere.
Abstract: A trunnion assembly (10) for adjusting a rotating cylindrical container (16) having a circumferential tire (7) is disclosed. The assembly (10) includes a rotating roller (11) supported between a pair of brackets with bearings (12) that are attached to a first base plate (13A) pivotally supported on a second fixed base plate (13B). An elongated arm (14) is secured to the first base plate (13A) at one end and secured to a guide base plate (15) at the other end. A pair of spaced guide rollers (16) are mounted on the guide base plate (15). The circumferential tire (7) is positioned between the guide rollers (16) and the rollers (16) are positioned within a barrier assembly (20).
