Vacuum Kneader

Our vacuum kneader has widely application. It is extensively seen in the industry such as silicone rubber, moulding rubber, hot melt adhesive, printing ink, painting, pigment, dyestuff, oil paint, and carbon material. In addition, the vacuum kneading device is an ideal tool for the other industries, including chemical industry, plastic, medicine, cosmetic, foodstuff, tape, urea-formaldehyde molding powder, starch, gum base, welding electrode, etc.

Working Principle
The vacuum kneader is a kind of high performance device for mixing material with ultrahigh viscosity. It utilizes the shearing force generated between two stirring paddles, as well as the shearing force between the stirring paddles and the kneading tank, during the rotation of the paddles. The material can be completely mixed, kneaded, smashed, and dispersed with our vacuum kneader.

A temperature adjustment device can be connected with our vacuum rubber kneader, such as oil circulation heating device, electrical heating unit, steam heating apparatus, or cooling water system.
