Donar DE-XRT Pro Sorting System

Wood waste recycling presents a sorting challenge where material quality is defined by internal properties invisible to the naked eye — wood waste streams contain a complex mixture of quality grades, moisture levels, and hidden contaminants such as metals, stones, and dense foreign objects, all commingled in unpredictable combinations. For wood recyclers and biomass processors, the ability to accurately classify wood by density and quality grade while simultaneously detecting and removing contaminants is the key to producing clean, high-purity wood fractions that protect downstream equipment, maximize recycling efficiency, and command premium market value. Intelligent dual-sensor sorting is the key to unlocking what conventional surface-only systems cannot detect.

The Donar DE-XRT Pro Sorting System leverages the cutting-edge fusion of Dual-Energy X-ray Transmission (DE-XRT) and high-resolution RGB (HR-RGB) imaging technology powered by state-of-the-art AI algorithms to accurately identify and classify wood quality grades by jointly calibrating wood density, dual-energy ratio (DER), characteristic absorption, and surface features — efficiently removing contaminants from wood waste, enhancing recycling efficiency, and improving material purity.

AI-driven surface feature recognition algorithms — trained on real-world production data using deep learning, with sorting precision refined continuously — ensure consistently high sorting accuracy across diverse wood compositions and contamination profiles — helping processors maximize quality-grade recovery, eliminate hidden contaminants, and deliver clean, high-purity wood output that protects downstream equipment and meets the exacting standards of modern wood recycling with unmatched confidence.
