The Effect of the Rotor’s Shape for the Mixing about the Mixing-Extruding Machine
The mixing-extruding machine is made up of mixer and unconventional double-cone screw extruder, which has both the excellent mixing capabilities and the continuous extruding characters. In the mixer chamber, the complex mixing motion of the blends is determined by the different kinds of forces acting on the blends. The different structure of the rotor, the distribution of the three direction forces is changed also。From the force analysis about the blends, there are three structure factors about rotor effecting the mixing process, such as the wedge angle θ of the rotor’s cross-section, the helix angle β of the rotor’s wing and the length of the wings. The best value of each structure factor can be gotten from theoretical analysis.
