Twin Screw Extrusion Granulation Line – Water Cooled Strips Series MMS-433-25

A twin-screw extrusion pelletizing line is an industrial production equipment used to process molten materials such as plastics, rubber, and chemical substances into granular products through extrusion. It is also referred to as a twin-screw extrusion pelletizing machine or a twin-screw pelletizing extrusion production line.

The key advantage of this equipment lies in its ability to uniformly mix, melt, and extrude materials, forming granules with specific shapes and sizes using molds. Thanks to the design of the twin screws, it is particularly effective in handling materials with higher viscosity and elevated filler content that pose challenges in processing.

Furthermore, the operation of the twin-screw extrusion pelletizing line is notably stable, resulting in higher production yields that can meet the demands of industrial production.
