Structure Characteristics Of Three Screw Extruder The Three Screw Extruder are arranged in a zigzag shape and rotate in the same direction, equivalent to two pairs of twin screws.
How to arrange the Three Screw Extruder Structure Characteristics?
The development and innovation of screw extruder is promoted because the application field of screw extruder is constantly expanded. Three screw extruder with three screw "one" arrangement and three screw triangle arrangement are new models developed in recent decades.
Whether it is a single screw or a double screw supporting the full weight of the screw is a screw end sleeve bearing. This cantilever structure makes the weight of the screw front section droop and the bearing at the other end of the great asymmetrical load, especially in the case of dynamic friction of the screw continuous operation, will inevitably affect the strength of the bearing structure, a long time, the screw will occur in the front section droop, affecting the smoothness of operation.
"A" word arrangement of two different Three Screw Structure Characteristics three screw equal length unequal diameter, the middle of the main screw diameter, two auxiliary screw diameter is small, the main auxiliary screw meshing with each other, reverse rotation. This design, enlarges the rolling area, strengthens the kneading effect, has the better plastic effect, not only increases the output, and the energy consumption does not increase much, because of the existence of the two meshing area, the rolling area doubled can shorten the screw length, reduces the negative impact caused by the screw cantilever.
The triple screw extruder with inverted shape is an innovation in the field of extrusion. Compared with the aforementioned two three-screw extruders arranged in the "one" shape, the equilateral triangle arrangement of the fully meshing three-screw extruders constitutes a unique three meshing zones, which has a very complex influence on the flow direction, velocity and spatial location distribution of materials. Make it can be small diameter, small aspect ratio of multi-screw combination to obtain high yield, high mixing quality effect.
