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 Washing Recycling Line | REHOBOTH Cleaning System

FEEDSTOCK‑LED WASHING LINE SELECTION

Configure sorting, size reduction, washing, separation and drying around the material entering your plant‑not around a fixed equipment list.

Compare dedicated routes for rigid plastics and PET, then define configuration: required material grades, drying targets and downstream granulation according to your feedstock, required throughput, available utilities and intended flake or pellet use.

Compare System Types Discuss Your Material

Choose the Right Plastic Washing Line

Start with polymer, item form and contamination. Confirm the final process against representative feedstock and the required dry‑flake or downstream pelletizing condition.

Compare Key Selection Factors

System family	Typical feedstock	Main cleaning concern	Configuration focus
Rigid Plastic Washing Line	Sorted HDPE, PP and other compatible rigid containers, ports or rigid	Labels, dirt, oils, mixed densities and stable moisture reduction	Sorting, crushing, friction washing, density separation, rinsing and drying
PET Washing Line	PET bottles or prepared PET packaging feedstock	Labels, caps, adhesives, density separation and final moisture	Pre‑sorting label removal, crushing, washing, separation, rinsing and drying

What Determines the Washing Line Configuration?

Incoming contamination

Identify labels, caps, metals, sand, oils, adhesives, organics and mixed polymers. Representative samples help define sorting and washing duty.

Required output condition

Define whether the line should deliver clean dry flakes or connect to downstream granulation, and which moisture and contamination checks are required.

Site and utilities

Confirm throughput, operating hours, water quality, power, heating source, drainage, floor space, labor plan and applicable local requirements.

How Waste plastic cleaning and granulation recycling system Works

REHOBOTH Closed-Loop Cleaning Line: Ensuring the cleaning process itself leaves no trace of contamination.A complete purification journey from waste materials to high-grade particles—achieving zero discharge of wastewater and exhaust gases within your facility.

Integrated Closed-Loop Cleaning Line:

Scrap - Cleaning -Crushing - Pelletizing - Environmental Exhaust Treatment - Water Treatment

Key Washing Process Decisions

SortingSeparate incompatible polymers, metals and non‑plastic contamination before size reduction.

Size reductionMatch crusher or granulator duty to item form, wall thickness and downstream washing equipment.

WashingSelect cold, hot, or friction stages around labels, oils, adhesives and surface contamination.

SeparationPlan density and solids removal around polymer combinations, caps, labels and fines.

Drying and transferDefine moisture target, flake collection and the interface with storage or granulation.

Plastic Washing Line FAQs

Here you can find questions and answers related to pelletizing line customization, service and quality:

What level of automation and technical support do you provide?

The system features centralized PLC control for real-time monitoring and adjustment. We provide comprehensive installation, commissioning, and operator training, backed by 24/7 remote support and a global spare parts network to maximize your uptime.

How energy-efficient is your granulation system compared to conventional models?

Equipped with permanent magnet motors and advanced electromagnetic heating, our system reduces energy consumption by up to 35% per ton of output compared to traditional setups, delivering a faster return on investment.

What is the key advantage of your closed-loop water circulation system?

Our closed-loop system recycles over 95% of process water, drastically reducing freshwater consumption and eliminating wastewater discharge. This not only cuts operational costs but also ensures full environmental compliance.

How does your system ensure the final pellet quality meets production standards?

Through a multi-stage process including friction washing, floating separation, and precision filtration, we achieve material purity exceeding 99%. The integrated degassing extruder removes moisture and volatiles, ensuring the pellets' mechanical properties meet manufacturing requirements.

What types of plastic waste is your system suitable for processing?

Our system is engineered to handle a wide spectrum of plastics, including PET bottles, HDPE containers, PP woven bags, and LDPE films. It effectively removes contaminants like labels, adhesives, and sand, transforming mixed waste into high-purity, reusable pellets.
