PRODUCT OVERVIEW
Designed around the production task.
High-speed friction washing for removing surface contamination from selected film and flake feedstocks before downstream separation and moisture reduction.
MATERIAL & PROCESS CONTEXT
Material, process and output context.
Technical configuration is available on request. Please share your material, output target and product specification with the Grace team.
CONFIGURATION ENGINEERING
Engineering surface-cleaning module around the actual material
A recycling system is defined from the actual feedstock and required downstream use, not from a headline model or capacity. Material condition, contamination, safety boundary and each process interface are reviewed together before a project configuration is released.
Material definition
Confirm polymer family, material form, incoming size, contamination profile, moisture, labels, metals, non-target fractions and any restricted or hazardous contents before selecting the route.
Process-route integration
The selected process interface is after size reduction or pre-washing and before rinsing or separation. Each module is balanced with its upstream preparation, downstream handling and the declared target material requirement.
Utilities, residue and safety
Water management, residue handling, ventilation, access, guarding and site constraints are defined with the actual material and local operating conditions; they are not assumed from a generic reference line.
Project confirmation
The final equipment list, operating window, controls and acceptance criteria are confirmed through project engineering, controlled technical review and the agreed validation plan.
FOR A TECHNICAL PROPOSAL
Information that lets us define the right line.
- Contamination profile, water condition, material form and downstream requirement
- Clear material photos or representative samples, including packaging and contamination condition
- Required target material, downstream use and any purity, moisture or handling expectations
- Factory layout, utilities, water-treatment boundary, safety rules and local regulatory requirements
- Required controls, service access, documentation language and project delivery expectations
This v2 Beta page presents the R&D-signed technical reference for the stated material and process scope. It is not a price, delivery, quality, certification or contractual performance commitment; the final project configuration and acceptance conditions remain subject to controlled engineering review.

| Model | Primary role | Applicable feedstock / condition | Candidate route capacity range | Key standard configuration | Selection boundary |
|---|---|---|---|---|---|
| GRFW500A-F | High-speed friction washing | PE/PP industrial and packaging film; low-contamination route | 300–700 kg/h | 18.5 kW · 1,080 rpm · Ø500 mm · 3,000 mm shaft · 6 screens | Candidate industrial-film route reference; contaminant profile, water condition and downstream separation require confirmation. |
| GRFW600B-F | High-speed friction washing | PE/PP agricultural film; silt around 40% and below 60%; straw may be present | 600–1,600 kg/h | 30 kW · 1,050 rpm · Ø600 mm · 3,500 mm shaft · 6 screens | Candidate agricultural-film route reference; final duty follows actual contamination and the complete washing route. |
| GRFW500-T | Three-shaft vertical friction washing | Post-consumer PET bottle or flake route | No standalone capacity published | 23.6 kW installed power · three-shaft vertical configuration | The controlled source only places this unit in a candidate PET route; final application and throughput require material-balance review. |

- Key standard configuration
- 18.5 kW · 1,080 rpm · Ø500 mm · 3,000 mm shaft · 6 screens
- Selection boundary
- Candidate industrial-film route reference; contaminant profile, water condition and downstream separation require confirmation.
GRFW600B-F
- Primary role
- High-speed friction washing
- Applicable feedstock / condition
- PE/PP agricultural film; silt around 40% and below 60%; straw may be present
- Candidate route capacity range
- 600–1,600 kg/h
- Key standard configuration
- 30 kW · 1,050 rpm · Ø600 mm · 3,500 mm shaft · 6 screens
- Selection boundary
- Candidate agricultural-film route reference; final duty follows actual contamination and the complete washing route.
GRFW500-T
- Primary role
- Three-shaft vertical friction washing
- Applicable feedstock / condition
- Post-consumer PET bottle or flake route
- Candidate route capacity range
- No standalone capacity published

Where capacity is shown, it is a candidate range of the cited recycling route, not a universal friction-washer promise. Cleaning effect and practical rate depend on contamination, material form, water condition, screen arrangement and downstream separation.
