Donar DE-XRT Sorter

Donar DE-XRT Sorter utilizes Dual-Energy X-ray Transmission Imaging and AI deep learning algorithms to accurately identify and classify wood quality grades by jointly calibrating wood density,  dual-energy ratio (DER), and characteristic absorption. It efficiently removes contaminants from wood waste, enhancing recycling efficiency, improving material purity, and protecting downstream equipment

Two X-ray Energy Levels:

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

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

【Softwood】 

✦ DER 1.1-1.3

✦ Density 0.35-0.55 g/cm³

【Hardwood】

✦ DER 1.5-1.8

✦ Density 0.65-1.05 g/cm³

【MDF】

✦ DER 1.2-1.6

✦ Density 0.65-0.80 g/cm³

【Contaminants】

✦ DER > 2.0

Technical Features 

● Superior Dual-Energy X-ray Transmission

Precise wood quality classification and efficient contaminant removal by measuring differences in density, dual-energy ratio (DER) and characteristic absorption

● 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

● Flexible Modular Design

Modular design of belt width from 1200 to 2800mm (1200/1800/2800) provides processors more flexibility, ideal for wood recyclers, recycled panel producers and biomass power plants

Benefits

✦ Enhanced Material Purity

✩ Precision sorting: Separates softwood, hardwood, MDF, and contaminants (metals, plastics, stones)

✩ Higher-quality recycled wood: Suitable for premium applications (furniture, construction)

✦ Reduced Processing Costs

✩ Less manual labor: 3-5x faster than manual sorting

✩ Lower contamination costs: Removes hazardous materials early

✦ Environmental & Sustainable Benefits

✩ Less landfill waste: >90% recovery rate (vs. 60-70% conventional)

✩ Lower CO₂ emissions: 75% less carbon than virgin wood

✦ Increased Revenue

✩ Higher resale value: Purified wood sells for 30-50% more

✩ Optimized resource use: MDF→biofuel, hardwood→furniture
