Planetary Screw Barrel

The planetary screw barrel of the utility model, because of the existence of the small diameter of the planetary screw in the spiral groove, the flow channel volume mutation, material flow space from large to small, and from small to large, at the same time with the rotation of the planetary screw, the material speed also fluctuates. When the material passes through the small diameter screw area of the planet, it is subjected to high deformation and tensile action, which can improve the effect of dispersing and mixing. The residence time of the material is much shorter than that of the single screw, which can not only strengthen the material mixing effect, but also improve the extrusion output. The extrusion characteristics of the planetary screw are more excellent.

Specification:

Planetary screw extruder is composed of central shaft, planetary shaft, rolling stuff barrel, case, heating and cooling parts, rozzel, and so on.

The structure uses model system, and has good flexibility.

Planetary screw extruder mainly are used for manufacturing thermal sesitivity materials hard and soft PVC and also for ABS, TPO, TPU, and the mixture of filler polyalkene and bond.
