Abstract: Disclosed is a plastic trim reclaim process that recycles otherwise wasted trim into for reuse or densified composite bricks for resale. The device combines four sections to process trim scrap from a typical plastic extrusion process. The four sections comprise an input and feed section, a grinding and pre-sizing section, a compaction and sizing section, and a repelletizing and recovery section. The final product takes one of two forms: a compacted plastic brick or pellet-sized beads that can be directly reused in a new extrusion process. The compaction and sizing section utilizes a heating chamber and ram to force ground trim through an extruder, which is then cut into sections to form brick. The repelletizing and recovery section utilizes an extrusion process that feeds into a cutting plate, whereafter the sized pellets are cooled to solidify their structure prior to being vacuum transported into a container for reuse.
