The twin-screw extruder has the advantages of strong adaptability, sliding conveying and self-cleaning, but its structure is complicated, the investment cost is high, and the corresponding maintenance and operation costs are also high. Therefore, the twin-screw extruder is generally used in the production of high-value-added aquatic products and pet feed, such as the production of eel, turtle and juvenile feed, because the price De his products in foro est sufficiens reddere geminae-stupra technology {{VII}} sumptus de vestibulum products; Alia specialis aquatilium pascitur, ut denique aquatilium feeds ({{VIII}} mm in diameter), summus adipem aquatic, et feeds et parva productio volumina et saepe mutantur formulationes et exiguam {XI}}
The development of twin-screw extruder is relatively late in China. For the medium-sized twin-screw extruder, due to the large range of raw material characteristics, the screw speed needs to be adjusted in a larger range, because its working principle is different from that of single Screw extruder has a big difference in specific structure, especially the arrangement of barrel, screw, thrust bearing and gear box is more complicated, which causes the {IV}} {et apparatu incremento
