Mathematics model and experimental study of mixing evenness of continuous mixer

According to the structure and operating principle of continuous mixer, the mixing evenness and the structure and application parameter were set up by using kinematics analysis and theory derivation. The mathematics model shows the relations between parameters are verified by full size experiment. Theory derivation established mathematics model describing the parameter relations between mixing evenness, mixer fullness ratio, mixer´s length width ratio and installation angle, and verified through experiment. The derived effective length width ratio which meets the needs of production quality requirement is obtained by using mathematics model and ways to increase mixing quality by improving fullness ratio so far as the structure parameter of the fixed finished mixer is concerned. The results showed that the finished mixer´s structure parameters are established, mixing evenness relies on material´s fullness ratio, and mixing quality can be improved by reducing mixer´s fullness ratio. Mixer´s length width ratio has greater influence on mixture mixing evenness.
