ABSTRACT:
A baler for baling polystyrene material which has a high bulk and low weight for subsequent recycling. The baler includes a ram, to compress the material past its form memory, which provides significant penetration over repeated cycles to compress the polystyrene into a bale, which is subsequently ejected through a bale door of the baler. The baler can either be manually controlled or automatically controlled, such as by an algorithm stored in a programmable logic controller. Feedback systems measure the length of travel of the ram and the pressure of the ram to determine the status of the baling operation, and can automatically provide for ejection of the baled material. The bale can either be manually strapped, automatically strapped, or no strapping of the bale may be required. The polystyrene material is chopped by a chopper system on the baler to break the material into smaller sections for baling. The baler also includes a vertical tamper to tamp the polystyrene down into the baling chamber.
