The machine is driven by a pair of blades that cooperate and rotate with each other, producing strong shear forces that cause the viscous material to react rapidly with chemicals and achieve uniform mixing and stirring. This machine is an ideal equipment for kneading, crushing, dispersing, and re polymerizing various chemical products of high viscosity elastoplastic materials and silicone products. It has the advantages of uniform stirring, no dead corners, and high kneading efficiency. Heating methods include electric heating, steam heating, etc. The machine is equipped with a vacuum system, which can work in a vacuum environment.
