Abstract
A continuous mixer includes a barrel with a hollow interior, and a pair of mixing rotors housed in the barrel and that rotate in mutually different directions, each mixing rotor including a mixing portion with plural mixing flights formed about an axial center of the mixing rotor and projecting radially outward. The mixing rotors have a center distance therebetween smaller than a rotation outer diameter of each of the respective mixing flights. An inter-rotor clearance, which is the smallest clearance between the mixing portions at each rotation phase of the mixing rotors in a cross section perpendicular to axial directions of the both mixing rotors, has a dimension allowing an extensional flow to be generated in a material passing through the inter-rotor clearance. The continuous mixer can reliably and efficiently mix a material having a large viscosity difference between a dispersed phase and a matrix phase.
