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.
For all compounds, the rolls were set to a temperature of 50°C at a speed of 19 rpm with a friction ratio of :1 and a mixing time of 20 min. For the reference compounds without MLG the second stage was not performed. ... Tworoll mills have been used for rubber compounding since the middle of the nineteenth century. Originally they were ...
