We recently prepared a novel compatible rubber blend based on chlorinated NBR and chlorinated EPDM by a simple two-roll mill mixing method . Polymer blends that do not contain fillers are practically insignificant for commercial applications. Therefore, the rubber blends are commonly mixed with fillers to form composites and the loading of ...
Laboratory two-roll mill blending: The pure elastomers and blends were compounded in a two-roll mill at 50 °C, following conventional procedures in rubber technology. Firstly the elastomers were mixed to prepare a master batch where the other ingredients were added and mixed until they were completely dispersed in the rubber matrices.

It aids in rubber blending by pulling the mix compound from the front roll of the mill and guiding it to the nip gap between the two mill rolls. Structurally, this machine assembly consists of a blender roll, a carriage unit with guide rolls, pressure roll and rear roll along with required automation.
The final mix compound is then dumped into a two-roll mill or a dump extruder and processed in the normal way. When the two tasks of dispersion and distribution are separated, your compound weight is relatively smaller in the larger lower machine. Hence, you can operate this ramless mixer at a higher speed.
A two-roll mill was used to make rubber-rubber blends (RRBs) of natural rubber (70phr) and butadiene rubber (BR) (30phr) with 10, 20, 30, 40, and 50phr of carbon black (CB). All of the blend composition's cure, morphological, and mechanical characteristics were tested and described in the paper.
Use powdered polymer and a small amount of Pellet feed normally around 5 to 10% of the total weight. Add the around 50% of powder polymer to the blend then add all of the pigments, additives and dispersing aids, then add the rest of the powdered polymer and pellet feed. Close the mixer and spin on high speed typically for 3 to 5 minutes.

Let me help you with a quick back of the envelope calculation. If you are using a 270 Liter Tangential Internal Mixer, you are engaging at least two units of 26″x84″ two-roll mills in the downstream section. Each 26″x84″ two-roll mill, requires around 180 kW (minimum) motor power – totaling to 360 kW (=180 x 2) only for the mills.
