The complete 180 type PE granulator boasts five core advantages: two-stage fine plasticization, thorough water removal, non-stop stable production, wear resistance and durability, and high-purity pellets. Different from ordinary single-stage PE pelletizing equipment, its primary and secondary two-stage structure completely solves industry common defects of soft PE materials such as loose plasticization, uneven mixing and incomplete impurity filtration. The core screw and barrel are processed with high-frequency quenching strengthening technology, and the feeding port is added with a wear-resistant alloy layer to resist sediment and dust impurities mixed in recycled PE materials, ensuring no easy wear or carbon deposition under long-term heavy-load production. Equipped with electromagnetic + heating ring dual-zone precise temperature control, left-right hydraulic non-stop screen changing and full-line variable-frequency speed regulation system, it accurately matches the low-temperature melting process of PE, eliminating material scorching and raw material residue. The finished pellets are compact, transparent, dry and non-adhesive, greatly improving market premium and product competitiveness.

With strong universal adaptability, the equipment can widely process various polyethylene materials including waste PE greenhouse films, packaging films, plastic bags, PE pipes, injection molding leftovers and drip irrigation tapes. The produced high-quality recycled PE pellets can be directly used for secondary processing such as film blowing, wire drawing, injection molding and modified filling, suitable for large-scale production of small and medium-sized plastic recycling plants, environmental protection recycling enterprises and plastic product factories.
