Donar DE-XRT Sorter

The Donar DE-XRT Sorter utilizes Dual-energy X-ray Transmission imaging and AI deep learning algorithms to achieve precise sorting of E-waste. By measuring the differences in absorption and penetration of dual-energy X-rays by different materials, it efficiently identifies and separates metals (e.g., copper, aluminum, precious metals), plastics and other materials, improving resource recovery rates while reducing manual sorting costs

Two X-ray Energy Levels: 

Low-energy X-ray (20-50 keV)

High-energy X-ray (80-150 keV)

【Plastic】

✦ High absorption at low energy (low transmission)

✦ Low absorption at high energy (high transmission)

✦ DER < 1.5

【Aluminum】

✦ Moderate absorption at low energy (medium transmission)

✦ Low absorption at high energy (high transmission)

✦ DER: 1.5-2.5 (between plastic and copper)

【Copper】

✦ Very high absorption at low energy (low transmission)

✦ Moderate absorption at high energy (medium transmission)

✦ DER > 2.5

【Silver】

✦ Extremely high absorption at low energy (very low transmission)

✦ Moderate absorption at high energy (medium transmission)

✦ DER: 3.0-4.0

【Gold】

✦ Almost complete absorption at low energy (near-zero transmission)

✦ High absorption at high energy (low transmission)

✦ DER > 5.0

Donar DE-XRT sorter accurately distinguishes different materials in E-waste based on their DER differences

Technical Features

● Superior Dual-Energy X-ray Transmission

Precise identification and separation of metals, plastics and other materials in E-waste based on absorption and penetration differences

● Proprietary AI Deep Learning Algorithms

Innovative simulation of manual picking operation by teaching and training the intelligent DE-XRT sorter all the standards and features of identification and sorting

● Reliable High-Performance Ejector System

High-speed and powerful air ejectors designed and produced in-house ensure accurate rejection and reliable performance at high-capacity sorting
