Two roll rubber mill - Wikipedia

Rubber compounding means incorporating rubber ingredients into a rubber mixture so it is evenly dispersed, then the rubber mixture is called a rubber compound. The mill aids in two main steps of rubber processing - mastication and mixing. Mastication is when the raw polymer is sheared and the broken down to create an easier flow. This allows for better incorporation of materials, which leads to the mixing component, when the other materials for a compound are added.

Mixing mills - DEGUMA-SCHÜTZ GmbH

Mixing mills (also rolling mills) are used for the manufacture of rubber compounds. A rubber base material is mixed with several additives, such as fillers, softeners, processing aids and colourants here. The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber in the nip between the two
