Abstract: A large tumbling device into which broken pieces of labeled glass such as beverage bottles, or cullet, are fed. After entering the interior chamber of the tumbler, the cullet is carried by a plurality of interior fins along the inside circumference of the tumbler to a point where the glass falls back to the low point of the tumbler. During this fall, the cullet passes through a flame generated in the interior cavity of said tumbler. The glass is heated to a temperature well below 600 degrees Fahrenheit (the temperature at which the molecular structure of glass begins to change) therefore ensuring that the processed glass retains its original properties. This process is repeated numerous times, ensuring that all of the foreign material is removed, before the cullet passes through the entirety of the chamber and is cooled to be processed into the desired grades.

Abstract: The present invention discloses a method of constructing collapsible raw material bins for a portable asphalt plant in such a manner that said raw material bins may be located on the same flatbed semi trailer as the rest of the asphalt plant. The collapsible material bins are constructed in such that, when not in use, they may collapse in an accordion-like fashion upon one another. This is done by having one wall of two of the bins constructed so that it may slide in and out within the respective bin. Additionally, the bins themselves are mounted on a sliding rail system which allows for the necessary movement of the bin walls. The end result of this design is that it provides a compact enough raw material bin system to allow it to be constructed on the same flatbed trailer as the asphalt tumbler, and yet provides a large enough raw material bin capacity to allow for the efficient operation of the portable asphalt plant.
