Power Consumption Analysis of Polymer Solids Discharging Process in Vane Plasticization Extruder

Abstract:

This paper deals with the study of power consumption in the discharging process of polymer particulate solids in a vane plasticization extruder. The structure and operating principle of the innovational vane extruder are completely different with conventional screw extruders. The process of conveying materials in vane extruder is based on volume transportation. Solids conveying zone is the first section of polymer processing in extruder. Large amounts of energy are consumed in the zone. The solids conveying process is composed of feeding, compacting and discharging process in the vane extruder. The discharging process is very unique and worthy of further study because of the particularity of the vane extruder. A mathematical model has been developed to analyze the power consumption in the process. The model shows the structural parameters have significant influence on the power consumption. In addition, the model is verified by experimental results.
