The raw materials for processing plastic granules include plastic powder and powders used to improve the physical properties of plastics, such as antistatic masterbatch, anti-blocking masterbatch, and pearlescent masterbatch. The plastic powder and various masterbatch powders are mixed using a stirring device. The mixed powder is then melted by heating to fully fuse the various raw materials. Afterward, the molten material is extruded into granules using an extruder. After cooling, the desired plastic granules are formed. However, during the storage of plastic granules, a certain amount of dust will adhere to them, which needs to be removed.

The first motor 3 drives the first gear 4 to rotate, which in turn drives the first stirring rod 5 and the second gear 6 to rotate. The second gear 6 then drives the second stirring rod 7 to rotate, thus stirring and cleaning the raw materials. Water is drained from the mixing tank 2 through the drain valve 9, and the raw materials are discharged from the mixing tank 2 through the discharge valve 8, passing through the drying chamber 1 and entering the collection box 10. The second motor 15 drives the first screw 17 to rotate, which in turn drives... The first moving block 18 moves within the first groove 16, driving the first limiting plate 19 to move. The first limiting plate 19 then pushes the second limiting plate 21 to move the push plate 20. The push plate 20 then tumbles the raw materials in the collection box 10. The hot air blower 11 blows air into the ventilation slot 13 through the guide pipe 12, and then blows air into the raw materials in the collection box 10 through the air outlet of the ventilation slot 13 to dry them. The guide pipe 12 blows air from the top of the collection box 10 through the square pipe 14 to dry them. After drying, the collection box 10 can be pulled out of the drying box 1.
