Study on the Pressure Distribution on Solid-Plug Conveying of Centrifugal Extruder

In this paper, a new polymer process machine--- centrifugal extruder is introduced. The performance of centrifugal extruder had been studied by theoretical analysis. The analysis shows that the centrifugal force field can provide the solid-plug conveying pressure sufficiently and stably, which can prove the industry practicability of centrifugal extrude. By further discussion, it shows that the important influencing factors on the pressure comprise the structural parameters of the rotors and the rotation velocity.
