Baler for polystyrene material

摘要

A baler for baling polystyrene material which has high bulk and low weight for subsequent recycling. The baler includes a ram 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 programmable logic controller. Feedback systems measure the length of travel of the ram and the pressure of the ram determine the status of baling operation, and can automatically provide for ejection of the baled material. The bale can either be manually strapped, automatically strapped, and in some events, no strapping of the bale is required. The polystyrene material is chopped by a chopper system on the baler to break the material into smaller sections for baling. The baler has been specially designed to uniformly densify and bale most poly foam materials in a high production environment. The high pressure hydraulic system delivers powerful compaction force, enough to compress polystyrene foam past most material's form memory. The compression ram travels to the bale ejection door to deliver uniform material compaction from the first cycle to the hale's last. Other material can be baled by the baler.
