Recently, the CJWH85 twin-screw pelletizing line developed by JWELL Company has been successfully put into operation in a well-known environmental protection enterprise in Japan, which is dedicated to the recycling and pelletizing of post-consumer PET (polyethylene terephthalate). With 220kW high-power motor drive, 700kg/h high capacity output and underwater pelletizing technology, this equipment has become a benchmark case for the transformation of Japan’s recycled plastics industry to low-carbon and high-efficiency.
Technology highlights: high energy efficiency, precisely adapted to Japan’s environmental protection needs
The CJWH85 twin-screw pelletizing line is optimally designed for PET recycling characteristics, and its core advantages include:
1. Twin-screw synergistic and efficient plasticizing
Adopting high torque isotropic twin-screw structure, the screw L/D ratio is scientifically proportioned to achieve uniform melting of materials at 400 rpm, effectively avoiding thermal degradation of PET and ensuring pure color and stable viscosity of regenerated particles.
2. Underwater pelletizing technology improves quality
Through the underwater pelletizing system (Water Ring Pelletizing), the high temperature melt is extruded by the precision die head and then instantly cooled and solidified, the output pellets have smooth surface and uniform size (adjustable range of particle size 2-5mm), which can meet the standard of high-end fibers or food-grade packaging recycled materials.
3. Intelligent Energy Saving Control System
Integration of PLC automation module and energy consumption monitoring system reduces unit energy consumption by 15%, which is in line with Japan’s industrial electricity standards and helps enterprises realize the goal of “carbon neutrality”.
4. Application Scenario: Cracking the Pain Point of PET Recycling in Japan
Japan, as a leading plastic recycling region in the world, has strict requirements on the purity of recycled PET and production efficiency. the CJWH85 pelletizing line has won the market’s acceptance by virtue of the following features:
High compatibility: It can handle a wide range of raw materials such as post-consumer PET bottle flakes, industrial waste silk, film, etc., with an impurity tolerance of 1.5%, adapting to the complex sources of recycled materials in Japan.
Capacity breakthrough: Stable capacity of 700kg/h significantly shortens production cycle time, helping customers to cope with the challenges of labor shortage and high operating costs in Japan.
Environmental compliance: Fully enclosed design with negative pressure dust removal device, VOCs emission during production is far below the limit value of Japan’s Air Pollution Prevention Law.
Customer Feedback and Industry Implications
The Japanese customer said, “The CJWH85 line performed well during the trial run, controlling the fluctuation range of melting index (MI) of the recycled particles within ±0.5g/10min, which fully meets the requirements for virgin PET replacement. Its low failure rate and modular maintenance design significantly reduced our downtime costs.”
According to the International Bureau of Recycling (BIR) data, Japan PET recycling rate for a long time ranked among the top three in the world, but the traditional equipment energy consumption and processing precision has become the bottleneck of the industry upgrading.CJWH85 landing, marking the first time that China’s high-end regeneration equipment to achieve large-scale application in Japan for the East Asian recycling economy cooperation to inject new kinetic energy.
