Extruder Screw - Model PLT-ES -Extruder Screw Design
The twin-screw extruder is characterized by the “building block” design of both the screw and the barrel. The extruder screw design consists of a number of components mounted on the mandrel, such as threaded elements, kneading blocks, toothed mixing discs, retaining rings, etc. The barrel is also composed of different barrel sections, such as fully enclosed, with exhaust port, with filling port.
First, the extruder screw design , according to the specific requirements of the material, recipe, the various screw components, and barrel components in order to combine, so as to ground to complete the set mixing task. You can also change the order of the screw and barrel combination, to achieve the best use of different materials, formulations, to achieve the purpose of a multi-purpose machine, a multi-purpose machine.
Second, another advantage of the extruder screw design is that the threaded components and barrel components can be partially replaced, avoiding the scrapping of the screw or barrel as a whole and reducing maintenance costs.
Third, the modular design of the barrel is usually embedded with bimetallic bushings to improve the wear resistance of the inner surface of the barrel. To achieve the temperature course, there is a separate heating/cooling design on each barrel, thus enabling a combination of cooling and heating functions.
