Roll temperature in calendering must be accurately controlled. The processing behavior of neoprene at the calender or mill is temperature sensitive and varies from one type of compound to the other. Generally, the temperature differentials of the calender rolls for neoprene calendering are: Top roll—90 C, Middle roll—85 C, and

May 06, 2010 The temperature of the rolls was set at 185 C with total compounding time of 25 min. These conditions have been selected in order to homogenize fillers in the PP matrix. The total mixtures of sample which is 200 grammes were loaded on the heated two roll-mill. First, the pure PP matrix was filled onto the rolls

Bledzki et al. (2005) conducted a comparative study of different compounding processes prior to compression molding. The fiber–matrix mixture, at a ratio of 1:1, was compounded using a twin-screw extruder (170–195 C for 4 min), a two-roll mill (180 C for 10 min), and high speed mixture (170–175 C and 10–15 mins)

Aug 12, 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″ 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
