JCD65 Underwater Pelletizing Twin-Screw Extruder

This JCD-65D two-stage co-rotating twin screw extruder is specially R&D for plastic high filler modification production, adopting a professional two-stage modular structural design and high-torque configuration, perfectly adapted to the high-proportion filling processing of various inorganic mineral fillers. Its first stage is for efficient plasticizing and preliminary mixing, the second stage for deep dispersion and homogenization, which can realize uniform mixing of plastics and various fillers with high filling ratio. Equipped with multi-channel high-efficiency vacuum exhaust, wear-resistant core components and large-capacity feeding system, the bimetallic wear-resistant barrel and reinforced tri-axle transmission box ensure stable and continuous production under high filler working conditions, with a production capacity of 500-10000kg/h. It is an ideal professional equipment for large and medium batch plastic filler modification production.

Adopt two-stage co-rotating twin screw design, the first stage realizes rapid plasticizing of raw materials and preliminary mixing with fillers, the second stage for high-efficiency dispersion and homogenization, ensuring uniform dispersion of high-proportion fillers in plastics and improving the physical properties of finished products.

Optimized screw element combination and large-capacity feeding system, perfectly adapted to the processing requirements of high-proportion inorganic fillers (calcium carbonate, talc powder, titanium dioxide, etc.), the filling ratio can be flexibly adjusted according to production needs.

Configurable with 2 or multiple vacuum vents to maximize the removal of air, moisture and volatile substances generated during the high filler modification process, effectively avoiding bubbles and defects in finished products and improving product density and quality.

Barrel and screw adopt bimetallic wear-resistant material lining, with high wear resistance and corrosion resistance, adapting to the long-term friction and wear of inorganic fillers during processing and extending the service life of equipment.

Various efficient screen changing methods (manual/automatic/multi-station) to meet the filtration needs of different filler raw materials; multiple optional pelletizing modes (water-cooled strand pelletizing/water-ring die-face pelletizing, etc.) , easy to switch and adapt to the pelletizing requirements of different filler modified products.

Support multiple feeding forms matching high filler modification, including forced powder feeding, side feeding, liquid additive injection system, adapting to the feeding requirements of powder fillers, granular plastics and liquid additives, ensuring continuous and stable feeding.

Power part is equipped with AC frequency conversion stepless speed regulation, which can finely adjust the process speed to match the optimal mixing and dispersion parameters of different filler ratios; reinforced tri-axle parallel transmission box with oil-immersed and forced cooling lubrication, with low liquid level alarm function, realizing high-speed, high-torque stable operation and adapting to continuous mass production.

Barrel is designed with multi-directional opening (top/bottom/side), easy to clean and replace raw materials, suitable for switching different filler modification formulas; the whole machine has a compact structure and reasonable layout, convenient for daily maintenance and operation.

This two-stage co-rotating twin screw extruder is specially developed for plastic filler modification, with strong adaptability to high-proportion fillers and stable production performance, widely applicable to the filling modification processing of various general plastics, and also suitable for the production of high-filler masterbatch, covering the following materials and production scenarios:

PE/PP/EVA/ABS/PS/PVC + calcium carbonate/talc powder/titanium dioxide/carbon black/silica and other inorganic mineral filler modification, suitable for low, medium and high proportion filling processing.

Production of calcium carbonate masterbatch, talc powder masterbatch, titanium dioxide masterbatch and other high-filler functional masterbatch, with uniform dispersion of fillers and stable product performance.

Filler modified raw material processing for plastic pipes, profiles, films, injection molded parts and other products, improving the rigidity, heat resistance and dimensional stability of finished plastic products.

Filling modification production of PPR pipe materials, PE cross-linked pipe materials, low-smoke halogen-free cable materials, adding inorganic fillers to improve the flame retardancy and mechanical properties of pipe and cable materials.

TPR/TPE/TPV filler modification, adding light calcium carbonate, talc powder and other fillers to optimize the product hardness and reduce production costs on the premise of ensuring performance.
