Description

Technical Field

[0001] The utility model belongs to the technical field related to cleaning powder and debris in plastic particles, and particularly relates to a device for removing debris in plastic particles. Background Art

[0002] Plastic pellet processing is the process of converting waste plastics into reusable plastic pellets through a series of processes.

[0003] The plastic pellet processing process involves multiple steps. First, raw materials are screened and sorted to ensure high-quality raw materials and that the resulting pellets meet the required quality. This is followed by pre-processing steps such as crushing, washing, and drying to remove impurities and prepare the plastic for further processing. Heating and melting the raw materials converts them into a molten state, and then compression and other steps form pellets. This process also includes filtration and pelletizing to ensure pellet quality and specifications. Finally, the processed plastic pellets are packaged for storage and transportation.
