1000kg/h Conical Twin Screw Extruder for Rigid Plastic Waste

Extruder for Rigid Plastic Waste Product Introduction 

The 1000kg/h Conical Twin Screw Extruder for Rigid Plastic Waste is designed for high-capacity recycling and re-granulation of rigid plastics. The 1000kg/h system melts and plasticizes PP, PE, ABS, PS, PVB, and PA scraps, then removes trapped air through vacuum degassing and filters impurities.

Its conical twin-screw design ensures uniform melting and high throughput, while modular dies enable processing of various polymer types. The system delivers continuous, stable operation, producing clean and uniform granules suitable for reuse in injection molding, extrusion, and other plastic processing applications.

Working Principle：

Plastic scraps are fed into the hopper of the conical twin-screw extruder. The screws melt and homogenize the material while conveying it forward. A vacuum degassing section removes trapped air and moisture. The molten plastic passes through a filtration system to remove contaminants, and finally, the extruded material is pelletized into uniform granules. PLC controls synchronize screw speed, temperature, and pelletizing process for consistent quality.
