The kneader is an ambitious equipment for kneading, blending, vulcanizing, and polymerizing high-viscosity, elastoplastic materials. It is used in the production of silicone rubber, sealant, hot melt adhesive, food gum base, and more. The kneader is a special type of mixing equipment, commonly featuring two Sigma blades arranged in an adjacent, differential speed layout, where one impeller rotates faster than the other to generate shearing forces. The varying impeller speeds allow the blended materials to be sheared quickly, ensuring uniform mixing.

The Vacuum Kneader is a type of kneader primarily used in the chemical production fields such as silicone rubber, glass glue, butyl rubber, and thermoplastic adhesive. A kneader typically consists of several major components, including the kneading system, vacuum system, heating system, cooling system, and electrical control system.
