ASPHALT MATERIAL RECYCLING SYSTEM AND METHOD

摘要

An asphalt roofing material recycling system and method is used to recycle new and used asphalt materials, such as asphalt shingles, rolled roofing and tar paper that may include granules, fibers or other particles. The asphalt material is broken up and separated and then provided to a recycling vessel. When the recycling vessel is operated in a cooled mode, dry ice may be added along with the asphalt material to be recycled. The dry ice removes any moisture present and super-cools the material making it brittle and easier to chip and break up. The recycle vessel includes a number of devices as well as at least one horizontal mixer element which stirs the material and makes sure all material is ground. The resulting course to fine powder can be sorted by screening and stored as power or compressed into bricks or briquettes for later use in making various products.
