How Selection Works
A practical four-step process focused on stable operation and consistent output.
Define Material Pair
State which plastics you need to split (e.g., PVC-from-PET) and target purity.
Confirm Feed Condition
Feed must be dry (<0.5% moisture) and size-classified (2–10 mm) for best results.
Size the Voltage
Rumtoo calculates the stage count based on the resistivity of the pair.
Key Advantages
Dry, Chemical-Free
No water or detergents needed. Low energy cost and no wastewater treatment.
Reach <50 ppm PVC-in-PET
Unlocks food-grade rPET pricing with high-purity separation.
Handles Black Plastics
Separates by surface charge, avoiding the limitations of NIR sensors.
Problem-Solution Fit
Unstable feedstock conditions reduce production consistency.
Engineering configuration is matched to material variability and throughput targets.
Inconsistent quality creates downstream process risk.
Process design focuses on output stability for downstream stages.
Frequent intervention increases labor and maintenance pressure.
Service-friendly structure supports efficient operation and maintenance.
Scaling capacity can disrupt existing line performance.
Modular integration supports phased expansion and retrofit planning.
Typical Use Cases
PVC-in-PET Purification
Removes residual PVC from washed PET flakes for bottle-to-bottle extrusion.
PE/PP Fraction Separation
Splits mixed rigid packaging where density differences are too small.
E-Waste Metal/Plastic
Recovers metal particles from cable jacket regrind in a dry process.
Technical Specifications
| Parameter | Specification | Notes |
|---|---|---|
| ES-600 | 300-600 kg/h | PVC/PET, ABS/PS |
| ES-1000 | 600-1000 kg/h | PE/PP and mixed rigid flakes |
Final purity depends on moisture, particle size, and material pair.
Why Choose Rumtoo
| Criteria | Conventional Setup | Rumtoo Solution |
|---|---|---|
| Process Stability | More fluctuation under feed variation | Designed for stable operation across variable feedstock |
| Output Consistency | Higher variation in downstream quality | Process control focused on consistent output |
| Integration | Higher retrofit complexity | Practical integration with existing lines |
| Lifecycle Support | Limited startup optimization support | Engineering support from planning to commissioning |
Frequently Asked Questions
What is an electrostatic separator?
