Shearing in roller gap. The controllable energy input by shearing is decisive. It can be specifically controlled by defined process parameters of EXAKT Three Roll Mills. All models offer a finely adjustable and consistently parallel gap. Combined with the roller speed, this results in a shear rate that can be flexibly adapted to any product.
Rubber - Processing, Vulcanization, Synthetic: Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or …
