RECYCLING APPARATUS AND RECYCLING MANUFACTURING METHOD FOR EXPANDABLE POLYSTYRENE INGOT PELLET AND STRUCTURE OF EXPANDABLE POLYSTYRENE INGOT PELLET

摘要

The present invention relates to a method and an apparatus for reproducing used styro-foam which reproduces used styro-foam into polystyrene ingot pellets or foamed ingot pellets, and the same ingot pellets, including: a step of collecting used styro-foam and washing the same; a crushing step of crushing dried styro-foam, washed by the washing step, into particle materials; a volume reduction step in which the crushed particle matters of used styro-foam are put into a volume reducer, so as to obtain a polystyrene resin; a pretreatment process in which a rod-shaped polystyrene ingot is continuously extruded and is re-processed into ingot pellets; and a bulk packaging the polystyrene ingot pellets extruded from the re-processing. [Reference numerals] (100) Collect and select used styro-foam; (110) Crush and grind the used styro-foam; (120) Volume reduction of the used styro-foam to a polystyrene resin; (130) Pre-process(polystyrene ingot cake); (140) Re-process(polystyrene ingot pellet); (150) Bulk packing
