At the core of our Ring Die Wood Pellet Mill lies a precision-engineered ring die and roller system—crafted from high-chromium alloy steel and treated with quenching technology to ensure exceptional wear resistance. This heavy-duty core enables the machine to process raw materials with a moisture content of 8-15% (optimal for pelletizing) into uniform 6-12mm pellets that meet international biomass fuel standards (DIN EN 14961-1).
