Abstract

See full text

The asphalt roofing material is delivered into a treatment chamber of a processor. Hot oil is passed through a jacket surrounding the treatment chamber. Heated asphalt forms a hot solid and/or a liquefied slurry. The hot solid and/or the liquefied slurry is then removed from the treatment chamber. The asphalt roofing material in the treatment chamber can be agitated to promote mixing. The asphalt is heated to a temperature in the range from 200 degrees Fahrenheit to 650 degrees Fahrenheit within the treatment chamber. The solid and/or liquefied slurry is milled after it has been removed from the treatment chamber. The solid and/or the liquefied slurry is cooled after it exits the treatment chamber, preferably to a temperature in the range of approximately 90 degrees Fahrenheit to 110 degrees Fahrenheit. The hot solid and/or the liquefied slurry is passed through a hammer mill after the hot solid and/or the liquefied slurry exits the treatment chamber to reduce the particle size of the solid particles.
