A Plastic Pellet Vibrating Screen, also known as a plastic pellet vibrating sieve, plastic granule vibrating screen, or plastic granule separator, is installed at the end of a plastic pelletizing line to separate pellets by size. It removes plastic pellet dust, long pellets, agglomerates, and oversized particles through pellet classification, producing more uniform plastic pellets for packaging and further processing.
The machine performs pellet dust removal, remove fines from plastic pellets, long pellet removal, and oversized pellet separation. Typical capacity ranges from 200–3,000 kg/h, with screen meshes from 2–100 mesh. It is suitable for PP pellet screening, PE, PET, ABS, PVC, PA, PC, masterbatch, and recycled plastic pellets.
Plastic pellets are not always uniform after pelletizing. They may contain plastic pellet dust, angel hair in plastic pellets, oversized pellets, agglomerates, and other unwanted materials generated during cutting, cooling, or conveying. These issues can affect packaging, automatic feeding, and downstream processing. A Plastic Pellet Vibrating Screen performs pellet dust removal, remove fines from plastic pellets, long pellet removal, and oversized pellet separation, producing cleaner and more consistent pellets before packaging or further processing.

For plastic pellet processing, vibrating screens are commonly selected for removing dust, long pellets, and oversized particles, while rotary drum screens are generally used for coarse material separation.
Plastic pellets are evenly fed onto the vibrating screen surface and move forward under vibration. Fine dust and small particles pass through the screen mesh for pellet dust removal, while qualified pellets are discharged through the product outlet. Long pellets, agglomerates, and oversized materials continue to the end of the screen and are discharged separately, completing pellet classification.
The appropriate screen mesh depends on pellet diameter and screening requirements.
| Pellet Size | Recommended Plastic Pellet Screen Mesh | Typical Purpose |
| 2–3 mm | 20–30 Mesh | Remove fine powder |
| 3–4 mm | 12–20 Mesh | General pellet screening |
| 4–5 mm | 8–12 Mesh | Oversized pellet separation |
| Above 5 mm | Customized | Special pellet sizes |
When selecting a plastic pellet screen mesh, consider pellet size, dust content, production capacity, and screening requirements. Different pellet screen sizes can be installed when production specifications change.
A Plastic Pellet Vibrating Screen removes fine powder, long pellets, agglomerates, and oversized particles in one screening process, helping produce plastic pellets with a more uniform size. Different screen meshes can be selected for various pellet specifications, and the screen can be replaced when production requirements change. The machine supports continuous operation in pelletizing lines and is available in carbon steel or stainless steel construction for different working conditions.
Plastic Pellet Vibrating Screens are used in PP and PE pelletizing lines, PET bottle recycling, plastic recycling plants, modified plastics, masterbatch production, engineering plastics, and extrusion pelletizing lines. They are also installed before the packaging process to separate qualified pellets from dust and oversized materials. Single-deck or multi-deck configurations can be selected according to different production capacities.
Plastic Pellet Vibrating Screens can be configured with single, double, or triple-deck screens to meet different screening requirements. Optional features include carbon steel or stainless steel construction, dust covers, mobile wheels, various discharge directions, and voltage options such as 220V, 380V, 415V, and 440V. Different vibration motor brands are also available according to project requirements.

A: The machine is suitable for PP, PE, PET, ABS, PVC, PA, PC, masterbatch, and recycled plastic pellets.
A: The screen mesh should be selected according to pellet diameter, dust content, and screening requirements. Different pellet sizes require different mesh openings.
A: Depending on the model, the processing capacity typically ranges from 200 kg/h to 3,000 kg/h.
A: The price depends on the screen size, number of screen decks, construction material, machine configuration, and required processing capacity. Providing your pellet size, material type, and production capacity helps determine a suitable model and quotation.
A: The service life of the screen mesh depends on the material being processed, operating hours, and maintenance conditions. The mesh should be replaced when it becomes worn or when screening performance changes.
A Plastic Pellet Vibrating Screen is used to remove pellet dust, fine particles, long pellets, agglomerates, and oversized materials after the pelletizing process.
