Laboratory two roll mill is one kind of plastic or rubber ,chemical material mixing equipment with adjustable gap between two parallel rollers ,this mixin machine equipment is used to masticat and knead natural rubber,synthetic rubber , EVA or PVC pellets and other chemical materials to get uniformly mixed raw materials and compounding additives evenly.


The two rollers of this kind of rubber mixing mill are made of hard chrome-plated mirror KDB material ,whose hardness can reach up to 70HB .


The roller are independently driven by geared motors,when processing ,these two roll would rotate at different speeds in relative directions.

After kneading and mixing for some time , the internal macromolecular chain would be broken accordingly, so that the various components inside the rubber compound are evenly mixed and dispersed,its physical properties  and chemical effects would change and contrast.


Throught the process of mixing and keading ,its properies would change , such as color dispersion, light transmittance, material appearance .and this ideal compounding material would be used to test as following purpose :


Color matching test

Soft and hardness test

Test stabilizer

Physical test

Chemical test

Various special ingredients

Small production operations

These lab rubber open mixing mills are mainly used in rubber and its products, plastics and its products, polyolefin, PVC, film, coil, profile production and polymer blending, pigments, masterbatch, stabilizer, stabilizer and other industries.
