What is a conical twin-screw extruder: It means that the shape of the screw in the extruder is tapered, and the directions of rotation of the two screws are the same. An extruder employing a conical twin-screw technique is referred to as a conical twin-screw extruder.
As we all know, the granulators currently on the market mainly include single-screw granulators, conical counter-rotating twin-screw extruders and parallel co-rotating twin-screw granulators. The only advantage of the single-screw granulator is the low cost, but there are defects in extrusion force, plasticizing performance and energy consumption, which can not meet the demand; the advantage of the tapered counter-rotating twin-screw extruder is that the extrusion force is large. However, the plasticizing performance is poor, the output is low, and the energy consumption is large; while the parallel co-rotating twin-screw granulator has good plasticizing performance, but the extrusion force is small, the output is low, and the energy consumption is large, so it is not in actual use. People's mind.
We know that the poor plasticizing performance will directly affect the quality of plasticized products, and the extrusion force will affect the output. At the same time, the energy-intensive equipment will put a lot of pressure on enterprises and society during the period of increasingly tight energy. . To this end, it is possible to design a granulator that can simultaneously satisfy the large extrusion force, good plasticizing performance, high yield and low consumption, and it has important economic value and popularization and application value.
In order to overcome the above disadvantages, the conical twin-screw extruder has good plasticizing performance and good extrusion force.
