Plastic Recycling Lines contain washing basins, crushing machine, agglomerator, drying unit, granule extruder and packaging unit.
Waste plastic recycling is recovery process of waste plastics and producing reusable raw material. Recycling of plastic starts by sorting waste material according to their resin types such as polyethylene, polypropylene, polystyrene, PET, PVC etc. Clean plastic waste can be melted and converted into pellets (granules) by using granule extruders.
Before extruding, a size reduction or densifying process might be necessary. This can be done by using crushing machines or agglomeration machines. Contaminated plastic material has to be washed and dried first. For example plastic shopping bags which has been recovered from city waste has to be washed thoroughly before granulated. These shopping bags are made with high density polyethylene (HDPE) or low density polyethylene (LDPE). Agricultural films such as greenhouse covers (LDPE) also can be recycled.
