37–450kW Degradable Polymer Masterbatch Extruder Line, 600kg/h Output

37–450kW Degradable Polymer Masterbatch Extruder Line, 600kg/h Output | HPL65 High Filler Masterbatch Twin Screw Extruder Line

HPL series twin screw extruders are widely used for masterbatch pelletizing production. Benefiting from high-torque structure, the machine features higher throughput and lower processing temperature compared with conventional low-torque extruders of equivalent dimension.

1. Conventional Masterbatch: color masterbatch, functional masterbatch, white masterbatch and black masterbatch
2. High Concentration Color Masterbatch: Suitable for PE, ABS, PS, EVA, PET, PP and other resins filled with high-content pigment and auxiliary additives.
3. Flame Retardant Masterbatch: For PP, PA, ABS, EVA, PBT compounded with flame retardants and related additives.
4. Special Functional Masterbatch: Anti-static, antibacterial and other customized functional filler-based masterbatch.
5. Masterbatch for Degradable Polymers: PP, PE, PS base masterbatch filled with high-concentration starch and relevant processing aids.

1. High output

   The throughput is 1–2 times higher than same-size low-torque twin screw extruders from other manufacturers. The largest model achieves maximum throughput up to 12 t/h per unit.

2. Energy-saving

   To reach identical production capacity, our smaller-sized extruder can replace larger-size equipment from competitors. For example, HPL51 delivers higher output than ordinary 65-type extruders, which helps reduce power consumption, raw material loss and workshop footprint. Heating rods replace traditional cast copper heaters to cut energy consumption by 15%–20%.

3. Advanced design

   High torque: The specific load factor of gearbox reaches up to 15 N·m/cm³;

   High speed: Maximum available screw rotating speed up to 1800 rpm;

4. Long service life

   The output shaft adopts unloaded bearing layout to effectively extend service life of vulnerable shaft bearings; the gearbox has a designed service life of 72,000 working hours (10 years).

5. Custom made design

   Available D/d ratio range:1.33～2.0;

   Customizable screw clearance with minimum gap down to 0.15 mm.

Transmission gearbox		The most advanced structure: bilateral symmetry gear drive system; it’s the same with the gearbox of German Flanders, Austria EssenBas.Now, the first-line extruder manufacturers in the world, such as Corperion,Berstorff, Leistritz, Toshiba, JSW are using the transmission structure; servcie life of the gearbox≥72000hrs.
Screw element		Various kinds of function elements, mixing and dispersing elements developed by ourselves can provie flexible production for kinds of materials and production process. Optional material: W6Cr5Mo4V2, Ni-based alloy, HIP alloy,Co-based alloy.
Barrel		Barrels are equipped with integrated wear-resistant alloy steel liner, which has the same composition and wearing feacture with W&P .Our mirror polishing seamless barrels, surface finish Ra0.2, verticality between barrels inner hole≤0.015mm；linearity of ten assembled barrels≤0.05mm； Optional material: W6Cr5Mo4V2, Nitriding steel, Tool steel, Ni-based alloy, HIP alloy,Co-based alloy.
