Computer simulation technology is used to define the problems in scale-up of extruders from 2.5 to 3.5, 4.5, 6.0, and 8.0 inches in diameter. It is shown that the conventional practice of scaling-up channel depths by the square root of the diameter ratio does not take full advantage of the potential output capacity of larger extruders and a faster rate of channel depth increase is proposed. It is also shown that inherent limitations resulting from decreasing barrel surface area and increasing flight clearance with increasing screw diameter will always result in a higher discharge temperature from the larger machine at any practical output rate. Frictional heat generation and heat removal requirements increase with increasing diameter, regardless of the scale-up system used, and these limit the output capability of the larger sizes at low discharge temperatures. 相似文献

Planetary roller extruders (PREs) are currently being employed first and foremost to feed calender/lamination units, for pelleting, for compounding powdered paint and for the reuse of recyclate. In these disciplines it is the most successful multi‐screw extruder. The range of materials that are compounded extends from classical plasticised poly(vinyl chloride) (PVC), via poly(propylene) (PP) and acrylonitrile‐butadiene‐styrene (ABS), through to powdered rubber. The planetary roller extruders convince in comparison with other compounding machines through the thermally carefully compounding, the balanced ratio of shear and heat transfer and the narrow residence time distribution. Experimental investigations to analyze the process behavior of PREs were carried out for the first time.
