SHJS double step compound unit features introduction
Structure form: The first stage is SHJ type high speed twin screw mixer. The second stage is SJ series low speed single screw extruder. The two are arranged vertically and vertically to form a double-step composite unit
Principle features and uses:
The advantages of the same direction twin screw and single screw are combined and complementary. Twin-screw forced conveying, high efficiency plasticizing mixing and shear dispersion. No head back pressure reflux. Avoids high shear overheating: single screw high pressure extrusion. But low speed and low shear. Also avoid overheating contradiction.
Combination of twin screw and single screw. The function decomposition of the process adds independent operating variables. It is conducive to the step-by-step optimization of each process:
Higher efficiency and productivity
It is widely used in various heat-sensitive material systems and large-capacity devolatilization operations. Such as: PVC, XLPE, halogen-free flame retardant cable material,
Shielding material, high concentration carbon black masterbatch and rubber after dehydration processing
