Product Description
20mm Twin-Screw Extruder | Twin-Screw Extrusion Granulator | Laboratory Twin Screw Extruder | Lab Granulation Line
This laboratory twin-screw extruder system provides comprehensive granulation capabilities for polymer processing applications, featuring precision control and robust construction for research and development environments.
Equipment Overview
| Product Introduction | During the polymer extrusion process, the twin-screw granulator performs shearing, mixing, and extrusion of conveyed solid melt polymer at controlled temperatures. The system manages physical state changes, mixing morphology, structural transformations, and the relationship between final mixture composition and properties. |
| Working Principle | Material enters through the feeding port and is kneaded into a ball under rotating screw action, rolling forward along the screw groove. Through shearing, compression, and stirring, the material undergoes further mixing and plasticization. Temperature and pressure gradually increase, creating viscous flow state conditions. The material passes through the machine head under controlled pressure and temperature to achieve the desired product shape. |
