Donar DE-XRT Pro X-ray Sorting System

E-scrap shreds present a sorting challenge where material value is often hidden beneath the surface — high-value fractions such as copper, aluminum, and precious metals are deeply embedded within complex waste streams, commingled with plastics and inert matter, making surface-only identification fundamentally insufficient for all sorting scenarios. For e-scrap recycling operations, the ability to see beyond surface appearance and accurately identify materials by their internal composition is the key to recovering maximum value from every shred — reducing reliance on costly manual sorting, improving resource recovery rates, and transforming complex e-waste into high-purity, high-value material streams.

The Donar DE-XRT Pro Series is an intelligent machine-vision-based sorting system that fuses advanced Dual-Energy X-ray Transmission (DE-XRT) technology with high-resolution RGB (HR-RGB) imaging, powered by proprietary AI algorithms, to achieve precise recovery of high-value fractions from e-scrap shreds — unlocking value that conventional sorting systems cannot detect. By measuring the differential X-ray attenuation of materials at two energy levels, combined with surface feature analysis via RGB imaging, the system efficiently identifies and recovers metals (e.g., copper, aluminum, precious metals), plastics, and other high-value fractions — improving resource recovery rates while reducing manual sorting costs.

AI-driven surface feature recognition algorithms — trained on real-world production data using deep learning, with sorting precision continuously refined through iterative optimization — ensure consistently high sorting accuracy across diverse e-scrap compositions and shred conditions — helping processors maximize high-value material recovery, minimize manual labor dependency, and deliver clean, market-ready output streams with market-leading reliability.

Two X-ray Energy Levels:

Low-Energy X-Ray (20-50 keV)

High-Energy X-Ray (80-150 keV)

Plastic

✦ DER < 1.5

✦ Low absorption at low energy; high transmission at high energy — lowest DER value

Aluminum

✦ DER: 1.5-2.5

✦ Between plastic and copper

Copper

✦ DER: 2.5–3.5

✦ Very high absorption at low energy; moderate absorption at high energy

Silver

✦ DER: 3.0–4.5

✦ Higher atomic number than copper; more pronounced absorption difference between energy levels

Gold

✦ DER > 4.5

✦ High atomic number; near-complete absorption at low energy

The Donar DE-XRT Pro Sorting System accurately distinguishes different materials in e-scrap shreds based on their differences in DER (Dual-Energy Ratio) and surface features.
Technical Features

● Dual-Energy X-ray & High-Resolution RGB Fusion

Industry-leading dual-sensor fusion combines differential X-ray attenuation analysis with high-resolution surface feature identification — delivering high-precision identification and separation of copper, aluminum, and precious metals in e-scrap shreds, even in heavily contaminated and compositionally unpredictable feed streams.

● Deep Learning Algorithms Trained on Production Data

AI-driven surface feature recognition algorithms, trained on real-world production data via deep learning, deliver sorting accuracy that matches and exceeds manual picking — and continuously improve through iterative model retraining, maintaining consistently high sorting performance as e-scrap compositions and contamination profiles evolve.

● Reliable High-Performance Air Ejector System

Powerful high-speed air ejectors, designed and manufactured in-house, ensure precise rejection and reliable operation even at high-capacity throughput.

● Flexible Options for Different Throughput Requirements

Available in two models with belt widths of 1300 mm and 2000 mm, providing processors greater flexibility to match different throughput requirements.

Typical Applications

✦ Printed Circuit Board (PCB) Sorting

Identification and separation of copper, aluminum, gold, silver and plastic substrates in PCBs

✦ Electronic Component Recycling

Recovery of precious metals from resistors, capacitors, connectors, etc.

✦ Waste Cable Processing

Separation of copper/aluminum cores from insulation layers (PVC/PE)

Automated intelligent sorting replaces costly and inefficient manual picking, significantly lowering per-ton processing costs while eliminating the quality fluctuations and safety risks associated with manual sorting — enabling recyclers to maintain a competitive edge as labor costs continue to rise.

Sorted copper, aluminum, precious metals, and engineering plastics achieve higher purity with lower cross-contamination, meeting the feedstock specifications of downstream smelters, compounders, and reprocessors — enabling recycled materials to command premium market prices and extracting greater economic returns from every ton of e-scrap.
