The machine generates strong shear force through a pair of cooperating and rotating blades, which rapidly reacts refined cotton or viscous materials with chemicals and achieves uniform mixing and stirring. This machine is an ideal equipment for mixing, kneading, crushing, dispersing, and re polymerizing various chemical products of high viscosity elastoplastic materials and CMC. It has the advantages of uniform stirring, no dead corners, and high kneading efficiency. Heating methods include electric heating, steam heating, etc.
