Zusammenfassung:	A processing line forms a desired end product for a plastic extrusion machine by supplying raw plastic material to a shredder. The shredder forms partially-fused, irregularly-shaped chunks of the raw plastic. The use of the shredder eliminates the requirement of extraneous matter separation prior to feeding of the shredder. The output of the shredder is conveyed to a ram feeder after passing material separators, such as a magnet and/or a metal detector or the like. The ram feeder forces the chunks to an extruder which ultimately supplies liquified plastic to a pelletizer to form pellets. The pellets are transferred to a storage vat for reuse.
