The open mill is a two-roll machine, which uses the shear force generated by the two rollers moving relative to each other at different speeds to plasticize. In the process of operation, the rubber material should be continuously triangle wrapped or crimped.

The kneading machine is a device that produces strong shearing action by a pair of blades (usually Z-shaped) that cooperate with each other and rotate, so that the semi-dry or rubbery viscous plastic material can make the material react quickly to obtain uniform mixing. It is an ideal equipment for mixing, kneading, crushing, dispersing and repolymerizing various chemical products of various elastoplastic materials with high viscosity. It has the advantages of uniform mixing, no dead Angle and high kneading efficiency. Widely used in high viscosity sealant, silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, also used in batteries, ink, pigments, dyes, medicine, resin, plastics, rubber, cosmetics and other industries.
