Research On Mixing Mechanism And Finite Element Simulation Of Rubber Continuous Mixer

Batch internal mixer is still the essential installation in rubber manufacturing production since it was invented in early 19th. However, due to the energy balance, fluidity of material in mixer and variation of batch to batch, the quality of sizing material is limited. So the concept of continuous mixing was established and such mixer was designed, as a result, to produce continuously is possible which improves the efficiency and quality of sizing material. But there's a limitation of this kind of mixer which restricts their application. Pelletizer is needed as the continuousmixer can not be able to process massive or less fluid material.1,Several documents or patents which are about mechanism and experiment of rotors, screws and continuous mixer are studied to post a new concept of double semi-jogged and heterodromous screwed continuousmixer.2,The configuration and mechanism of screw from extruding machine and rotor from internal mixer were combined for continuous mixing of massive rubber material.3,Design the barrel and helicopter for the continuous rotor, and mechanism of this new kind of continuous mixer is established.4,Based on the analysis of several 3D hardware models, SolidWorks is used to model the rotor of continuous mixer in 3D and ADINA is served for force analysis.5,ADINA is used to simulate the effect of mixing which based on analysis about fluidity of sizing material at different area of rotor.The design of double rotor continuous mixer in this paper is a combination and creation of existed internal mixer and extruding machine. It lays the foundation for development and industrialization of continuous mixer.
