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 ...
Apr 27, 2015· 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″ tworoll mills in the downstream section. Each 26″x84″ tworoll mill, requires around 180 kW (minimum) motor power – totaling to 360 kW (=180 x 2) only for the mills.
