Vacuum kneaders are mainly used in chemical production fields such as silicone sealant, glass glue base, butyl rubber, hot melt adhesive and other materials that are prone to bubbles. The working principle is that a pair of mutually cooperating and rotating paddles Sigma (or Z-shaped) produce strong

Kneader can be used in semi-dry or rubbery viscous materials for reacting and mixing quickly. This is due to the strong shearing fuction of a pair of cooperating and rotating Σ blades in the kneader. And the materials are further uniformly mixed after rapid reaction. Kneaders play an important role
