The sieve of the granules machine is a component that plays a key role in the plastic extrusion process. It is located at the extrusion head and is responsible for filtering and separating the molten plastic material to ensure consistent size and quality of the final pellet output. This article will introduce the plastic granules manufacturing machine screen and its important role in the extrusion process.
Structure and function of granules machine screen
The screen of a PVC dana making machine usually consists of a series of fine mesh holes. The size of these mesh holes can be adjusted according to the requirements of the product. The main function of the granules machine screen is to filter out the impurities, foreign matter, and insoluble particles in the molten plastic material to ensure the purity and consistency of the material in the extrusion process.
The presence of the screen helps to control the pressure during the extrusion process and prevents excessive extrusion pressure from adversely affecting the pelletizer. It effectively prevents plastic pellets from clogging the extrusion head during the extrusion process, improves productivity, and protects the pelletizer.
Maintenance and cleaning of PVC dana making machine screens
Maintenance and cleaning of plastic granules manufacturing machine screens are essential to keep the extrusion process running properly. Regular cleaning and replacement of screens prevent clogging and accumulated contaminants from adversely affecting the extrusion process while extending the life of the granules machine.
Granules machine screen selection
When selecting a PVC dana making machine screen, the proper mesh size needs to be determined based on the nature of the molten plastic material, pellet size requirements, and other factors. Different plastic types and production requirements may require different screen sizes to achieve optimum extrusion results.
The screen of a granules machine plays an important role in the extrusion process. It not only helps to control pressure, prevent clogging and ensure product quality but also extends the life of the plastic granules manufacturing machine.
