[0044] Working principle: When the pulverizing device for processing plastic particles is in use, the pulverizing mechanism 4 is started to drive the pulverizing roller 41 to rotate, so that the plastic on the pulverizing roller 41 is pulverized, and the processed plastic falls on the screening mechanism 3. The small particles of plastic are collected under the action of the screening net 34, and the remaining large particles of material roll into the inside of the conveying mechanism 2, and then the conveying mechanism 2 is started to drive the spiral blade 23 to rotate, so that the large particles of plastic are transported to the pulverizing roller 41 for secondary processing.
