    • 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.
    • 沥青屋顶材料被输送到处理器的处理室中。 热油通过围绕处理室的护套。 加热沥青形成热固体和/或液化浆料。 然后将热固体和/或液化的浆液从处理室中取出。 可以搅拌处理室中的沥青屋顶材料以促进混合。 将沥青加热至处理室内从华氏200度至华氏650度的温度。 固体和/或液化浆料在从处理室中取出后被研磨。 固体和/或液化的浆料在其离开处理室之后被冷却,优选在约华氏温度至华氏110度的温度范围内。 热固体和/或液化浆料在热固体和/或液化浆料离开处理室之后通过锤磨机,以减小固体颗粒的粒度。
