ABSTRACT:
An asphalt roofing material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill, to reduce the asphalt material granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled, either during heating and milling by continuously venting the heated milling apparatus, or before the heating and milling in a drying apparatus. The heated milling apparatus preferably includes a rotatable milling vessel rotated at an acute angle with respect to the horizontal plane and having an opening that provides continuous venting. The rotatable milling vessel includes a plurality of mixing members, such as rods or paddles, extending from an interior surface and preferably arranged in a helical pattern to force the asphalt material away from the opening. The asphalt material recycling system further includes a storage apparatus for storing reduced asphalt material and a filter apparatus for filtering reduced asphalt and removing foreign objects therefrom.
