Which information is needed to configure a plastic granulation line?

Provide the polymer, material form, contamination and moisture condition, hourly throughput target, available utilities, plant space and required pellet quality. These inputs determine pretreatment, feeding, extrusion, filtration, degassing and cutting choices.

Should film, rigid plastic and PET use the same pelletizing line?

Not usually. Low-bulk-density film, rigid regrind and moisture-sensitive PET have different feeding, drying, degassing and processing requirements, so each should be evaluated with a suitable line configuration.

When is a washing line required before granulation?

A washing stage is normally considered when feedstock contains dirt, labels, oils, adhesives or other contamination that cannot be controlled by sorting alone. Clean in-house scrap may only require size reduction and controlled feeding.

How should a buyer evaluate pellet quality during line selection?

Agree on representative feedstock and target checks before configuration. Relevant checks may include pellet consistency, contamination, moisture, filtration performance and suitability for the intended downstream process.

Plastic Recycling Granulation System

Material-led line selection

Configure a complete pelletizing process around your material—not around a standard machine list. Compare dedicated systems for film, rigid regrind and PET, then define pretreatment, feeding, extrusion, filtration, degassing and pellet cutting for your production conditions.

REHOBOTH supplies plastic recycling and granulation systems for post-industrial and selected post-consumer feedstocks. The correct configuration depends on polymer type, bulk density, contamination, moisture, printing, required throughput and the intended use of the pellets. Use this page to compare the main line families and identify the information needed for technical selection.

Compare Plastic Granulation System Types

Start with material form and condition. Final equipment selection should be confirmed against representative feedstock and the required pellet output.

Compare Key Selection Factors

System family	Typical feedstock	Main processing concern	Configuration focus
Film Plastic Recycling Line	PE/PP film, bags and other low-bulk-density flexible scrap	Stable feeding, moisture, printing and volatile removal	Size reduction or compaction, controlled feeding, degassing and filtration
Rigid Plastic Recycling Pelletizer	Sorted rigid regrind such as PP, PE, PS, ABS, PA or compatible blends	Particle consistency, contaminants and screen loading	Feeding, screw configuration, filtration and pellet cutting
PET Plastic Recycling Pelletizer	Prepared PET flakes from a controlled upstream process	Moisture control and thermal history	Drying or conditioning, stable extrusion, filtration and pellet handling

What Determines the Right Line Configuration?

Feedstock condition

Identify polymer, material form, bulk density, particle size, moisture, labels, ink, oils and other contamination. Mixed or unknown material requires evaluation before equipment is selected.

Required pellet output

Define how the pellets will be used and what must be controlled: consistency, contamination, moisture, color change, filtration demand and packaging method.

Plant constraints

Confirm target throughput, operating hours, available power and water, floor space, ceiling height, labor plan, local environmental requirements and upstream or downstream interfaces.

How Waste plastic recycling and granulation system Works

A pelletizing line is a one-stop, efficient, and sustainable solution for recycling a wide range of plastic materials.

The working process of plastic granulation line series:

Plastic granulation production line: belt conveyor - extruder feeding - main extruder - vacuum degassing - filter screen - die face cutting machine - vibrator - packaging.

Key Process Decisions

PreparationSort, wash, dry, shred or compact according to contamination, moisture and material form.

FeedingMatch the feeding method to bulk density, bridging tendency and the required steady output.

ExtrusionSelect the screw and processing arrangement for the polymer, blend and thermal sensitivity.

Melt controlPlan degassing and screen changing around volatiles, printing and contamination level.

Pellet handlingChoose cutting, cooling, drying and collection around resin behavior and pellet requirements.
