New Generation 150-type Plastic Pelletizing Machine – Medium-sized Full-automatic Waste Plastic Recycling Pelletizing Equipment with Moderate Configuration

In the field of medium and small-scale plastic recycling processing, the 150-type plastic pelletizing machine has become the core model with the strongest industry versatility and the highest production return rate at present, relying on its moderate production capacity, solid body structure and high energy efficiency. Most medium-end pelletizing equipment has common defects such as thin body frame, non-wear-resistant screw, high heating energy consumption, uneven discharging and simple post-processing structure, resulting in unstable mass production, inconsistent pellet quality and high operation and maintenance costs.

Our newly upgraded high-configured 150-type plastic pelletizing machine is fully equipped with an industrial thickened body, high-frequency heat-treated wear-resistant screw and barrel, electromagnetic energy-saving heating system and frequency-conversion linkage post-processing complete set. It realizes a fully automatic closed-loop production process including feeding, extrusion, filtration, cooling, pelletizing, dust removal, screening and material storage, perfectly meeting the stable mass production needs of medium-sized recycling factories.

The complete set of 150-type plastic pelletizing machine features five core advantages: high wear resistance, large production capacity, low energy consumption, stable operation and high-quality finished products. Different from ordinary low-end 150-type models, all core extrusion components are strengthened by high-frequency quenching treatment, featuring high hardness, wear resistance and carbon deposition resistance, which are not easy to be scratched or damaged during long-term processing of mixed materials and impure recycled materials.

The thickened channel steel frame improves the overall stability of the equipment and eliminates jitter and deviation during high-speed extrusion. The centralized electromagnetic heating ensures fast temperature rise, uniform temperature control and significant power saving. Equipped with complete post-processing devices including shaking and blowing unit, vibration screening and automatic material storage, the finished plastic pellets are clean, regular and high in purity, greatly improving the market price and product competitiveness. The equipment is applicable to both wet and dry raw materials, with fast startup, low failure rate and single-person operability, serving as the core main equipment for medium-sized plastic recycling mass production.

This equipment is widely suitable for recycling and pelletizing of various raw materials such as PP/PE films, plastic woven bags, pipe crushing materials, injection molding leftover materials and daily waste plastics. The produced pellets can be directly used in downstream production processes including injection molding, blow molding and extrusion modification. It is applicable to mass production of medium and small-sized plastic recycling processing plants, plastic product factories and environmental protection recycling enterprises, with wide application scenarios and fast return on investment.
