The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine will show you how: how a twin screw extruder is composed

The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine tells you that the twin screw extruder is composed of transmission device, feeding device, barrel and screw. The effect of each part is similar to that of a single screw extruder. Conical Twin Screw and The Barrel for Plastic Profile Machine manufacturer tells you that the difference between the single screw extruder and the twin screw extruder is that there are two parallel screws placed in the "∞"-shaped cross section of the material profile.

The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine tells you that the twin-screw extruders used for profile extrusion are usually tightly meshed and rotate in different directions. Although a small number of them are also extruded with co-rotating twin screws, they are generally compared Operating at low screw speed, about 10r/min. High-speed meshing co-rotating twin-screw exiting machine, used for compounding, exhaust or as a continuous chemical reactor.
The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine tells you that the speed of the large screw of this type of extruder is planned to be 300-600r/min. The non-intermeshing extruder is used for mixing, venting and chemical reactions, and its transport mechanism and intermeshing type The extruder is very different and closer to the transportation mechanism of the single-screw extruder. Although the two are essentially different, after 500 hours of routine maintenance and use, there will be iron filings or other impurities from the gear in the gearbox. Therefore, the gears should be cleaned and the gearbox lubricant should be replaced at the same time.
The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine tells you to check the extruder comprehensively after a period of use to check the tightness of all screws. If there is a sudden power failure during production, the main drive and heating are interrupted. When supplying power, the extruder must be started after heating each section of the barrel to the specified temperature and keeping it warm for a period of time. The manufacturer of Conical Twin Screw and Barrel for Plastic Profile Machine tells you that if you find the surface and the pointer full degree of rotation, you should check Whether the contact of the thermocouple equilateral line is excellent.
