Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was
Chaffee then created the two roll rubber mill which shears and mixes the rubber by having two rolls rotate in opposite directions, at different speeds. The two roll rubber mill is used in almost every rubber production facility today. Many other inventors created rubber mills with varying degrees of similarity to Chaffee's initial designs.

Apr 27, 2015· Each 26″x84″ two-roll mill, requires around 180 kW (minimum) motor power totaling to 360 kW (=180 x 2) only for the mills. For a similar capacity mixer, a TSS downstream will not seek more than 300 kW power (again, there is energy-efficient models available here).
The rubber blend was mixed in an open two-roll mixing mill for 5 min at 80°C. Then, the ethanolic CNT suspension was added very slowly. The mixing time for the incorporation of the nanotubes was about 15 min. Finally, the curing chemicals were incorporated into the composites at room temperature.

Generally, the blending of two or more types of rubbers is a useful and important way for the preparation and development of rubber blends with properties superior to those of individual constituents, which is also beneficial for improving damping and physical properties [13,14].In recent years, much attention has been paid to prepare wide temperature range of damping materials by blending.
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.
