[0002] When polyolefin cable materials are produced, the plastic particles are mostly transported by air conveying. This method can cool the cable materials, achieve good conveying efficiency, and has the advantages of easy installation. After the polyolefin cable materials are extruded, they rub against the pipe wall during the air conveying process and easily form plastic ribbons. The ribbons are formed by the friction between a large number of plastic particles and the pipe wall, which is not easy to clean and prevent. This kind of ribbon is very thin and light, so it is difficult to screen out through the vibrating screen. It often appears in the plastic particles, causing trouble for customers in the use of plastic particles and leaving a bad impression on customers.
