Vacuum degassing system for granular or powdered fillers

The new vacuum degassing system is intended for the ZSFE twin-screw side feeder. This side feeder is used in combination with twin-screw extruders of the ZE UTX and ZE UT series. The new degassing system is for the efficient removal of high air volumes when processing plastics with additives. This system sets new standards in terms of compounding productivity and cost effectiveness. Depending on the apparent density of the filling agent, the output can be almost tripled as compared to side feeders without degassing system. The optimum field of application for this system is the compounding of compounds filled with talc, wood flour, light-weight chalk types or other high-volume additives. With fillers of low apparent density, the hollow spaces between the particles are filled with air. This air volume is not required for compounding and limits the output rate of the side feeder. The vacuum degassing system removes the air before the fillers reach the processing chamber of the extruder and reduces the volume, thus increasing the apparent density. Consequently, the degassing system allows the filler share used in the process to be increased. The degassing system is equipped with an adjustable vacuum pump and a special non-metallic non-woven filter.
