The difference between open mixer and internal mixer

The open mill is a two-roll mill, which uses two rollers with different rotation speeds to generate shear force to masticate. During the operation, the rubber material should be continuously triangulated or crimped.
  The internal mixer uses the internal design of the blades to produce a regular contraction of the space when the relative movement is performed to generate shearing force, without manual operation, saving labor.
  The open mill has a simple structure and low cost, but the labor intensity is large, the pollution is large, and the worker's body is harmed.
The    internal mixer is more expensive, but it can be heated, and there is a pressurized internal mixer that can be used to process difficult-to-plasticize materials. Low labor intensity and strong adaptability.
The    internal mixer is a high-strength intermittent mixing equipment developed on the basis of an open mixer. Therefore, the appearance of the internal mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plasticizing and mixing, and it is still being developed and improved.
   kneader is a pair of mutually matched and rotating blades (usually Z-shaped) to produce strong shearing effect, so that semi-dry or rubbery viscous plastic materials can react quickly to obtain uniform mixing and stirring equipment. It is an ideal equipment for mixing, kneading, crushing, dispersing and re-polymerizing various high-viscosity elastoplastic materials. It has the advantages of uniform mixing, no dead corners, and high kneading efficiency. It is widely used in high-viscosity sealants, Silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, also used in batteries, inks, pigments, dyes, medicine, resins, plastics, rubber, cosmetics and other industries.
