Our advantages
1. High output
The output is 1-2 times larger than the same size extruder from
other lower torque twin screw extruders.
The biggest extruder can output up to 12T/h per set.
2. Energy-saving
For the same output , our small size extruder can replace the big
size of other extruder, such as our HPL51 has more output than
other 65 extruder , smaller extruder, less energy consumption,less
material consumption, smaller production areas.
And we use heat rod instead of cast copper heater, which can save
15%-20% energy.
3. Advanced design
High torque: carrying capacity factor of gearbox up to 15Nm/cm3;
High speed: max. 1800rpm/m；
4. Long service life
bearings on output shaft 2 without load, which greatly extended the
service life of the bearings on the weak axis , gearbox life can
reach 72000 hours (10 years)；
5. Custom made design
Wide D/d choice:1.33～2.0;
Custom made clearance: minimum clearance can be 0.15mm；
Parts and advantages
| 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. |
| Torque limiter |  | Steel ball type safety clutch + torque limiter Made in Germany have the characteristics of accurate torque
protection, high repeatability and quick reset. |
