To provide a viscous material kneading method for uniformly dispersing a viscous materials different in viscosity such as a rubber, a thermosetting resin or the like under a solventless condition while shortening a kneading time to enhance productivity, and a kneader therefor.
In the viscous material kneading method for kneading viscous materials 102 and 103 different in viscosity, the viscous materials 102 and 103 are frozen and embrittled and subsequently ground into a powdery form to be mixed with each other. The obtained mixture (n) is continuously and quantitatively supplied to the bank 260 between kneading rolls 211 and 212 and kneaded while wound around one kneading roll 211 while performing convection/substitution by the grooves 215.
