Three screw plastic extruder Advantages:
The arrangement of three screw ensures excellent self cleaning effect, compared with the traditional twin screw extruder, the screw meshing area has doubled, greatly improving the mixing effect of the screw. In many working conditions, it can replace the traditional internal mixer and reciprocating single screw extruder:
- Fast plasticizing performance
- Better mixing effect
- Saving energy and increase output
- Low L/D ratio, saving workshop space
Main Features
- Three screw extruder is faster processing in plasticification and better mixing effect than twin screw extruder,
- The material stay at high temperature condition for a short time, which can save 30% -40% energy.
- Three screw construction with parallel diameter in same direction.
- High shear efficiency and good plasticizing effect.
- Good practice and dispersal effect.
- High output and low energy consumption.
- Good exhaust performance.

Three screw Parallel Co-rotation screw extruder has arrange all of internal screws as like “-” shape, High speed Co-rotation provide the material to go throughout strong shearing, squeezing, kneading, grinding, milling and final and better homogenization and dispersion. The three screw extruder has one unique high shearing area than the common twin screw extruder, which provide more than once time in plasticification and blending effect. Twice than two screw extruder in processing capacity and yield, It mainly because the upgrade surface area and speed ratio as well as devolatilization have greatly improved.
Application:
- High distribution, high filling capacity. Such as polyolefin modification, engineering plastic modification, and so on.
- Mixing, Degassing and Vaporizing, and homogeneous residence time for high reactive extrusion. Such as: XLPE cable, silance crosslinking cable, TPE, etc
- High concentration of masterbatch and other functional masterbatchs with high dispersing performance, such as high concentration black, white masterbatch, high filling flame retardant, semiconductive material,etc
- Online compounding molding for film, board and injection parts, such as: breathable film, long glass fiber reinforced plastic structural parts.
