Extruder Feeding System

The Extruder Feeding System is designed to transfer PVC dry blends and suitable powder or granular materials from storage silos or buffer hoppers to extruders. Depending on material characteristics and production requirements, the system can be configured with vacuum conveying or flexible screw conveying to ensure a reliable material supply. **Vacuum Feeding System** The vacuum feeding system uses negative pressure to convey materials through an enclosed pipeline into a receiving hopper above the extruder. A typical configuration includes a suction lance, vacuum blower, receiving hopper, filtration system, and discharge valve. This solution reduces manual material handling and helps minimize dust emissions. **Flexible Screw Feeding System** The flexible screw conveyor uses a rotating shaftless spiral inside a flexible conveying tube to transfer materials to the extruder. Its flexible design allows curved conveying routes, making it suitable for installations with limited space or complex equipment layouts. **Customized Solutions** Conveying capacity, feeding method, pipeline layout, and control functions can be customized according to material characteristics, conveying distance, extruder capacity, and factory layout. The system helps maintain a stable material supply, reduces manual feeding, and supports continuous extrusion production.
