2023 Komptech Stonefex 3000E

The Stonefex stone separator delivers exceptionally effective removal of stones and inert materials from biomass fuels. Using a patented system that combines pressure and suction blowers, it generates a precisely controlled airflow inside the expansion chamber, ensuring stones and other heavy contaminants are cleanly separated from wood material. The result is a significantly cleaner, higher‑value fuel capable of achieving better market prices. Even material streams once considered unusable due to high stone content can now be efficiently processed into a profitable fuel product.
