    摘要: For almost 100 years, extruders have been built in such a manner that at a predetermined screw diameter, a corresponding throughput capacity is achieved, depending on the process conditions.To increase the output capacity, the screw diameter is generally increased in accordance with the physical laws of similitude. The length-to-diameter ratio remains the same, or the extruder becomes longer. This leads to the result that an engineer strives to use an extruder having a small screw diameter.In order to avoid the disadvantage of space-intensive extruders, fast-turning single-screw extruders have been developed in the past 10 years. Extruders having a screw diameter of 35 mm to 100 mm and having a length of 30 D to 40 D are usual in practice.Ultimately, however, all concepts usual on the market fail to implement a universal extruder.The invention is based on the task of presenting a universal concept of a single-screw plastification machine. The invention discloses a squat screw having a diameter of at least 200 mm and having an active length L that has a ratio L/D to the screw diameter D of 1 to 8.
