In continuous kneading, for stable -state production the feeder that feeds raw material and the heater that heats objective material must be controlled with consideration of the dynamics of the kneader.
In this paper, kneader dynamics was studied by examining responses in the realtime region and the frequency region, between variation of feed rate or kneading temperature and variation of kneading torque, which represents the state of flow of objective material. From this analysis, it was found that the response in the low -frequency region is most remarkable. The results showed that kneading can be performed in stable state by avoiding variation of feed rate and heating. Continuous kneading of electrically conductive resin was carried out with control of the feeder that took the dynamics into consideration. It was confirmed that variation of electrical conductivity of the electrically conductive resin could be made small, and that the effectiveness of control was remarkable when the flow state of objective material in the kneader was plug flow.
