DH500 Screw Feed


DH500 Briquetting And Compacting Roll Press

The DH Series machines feature rolls located symetrically between two bearings, allowing for greater roll separating forces. The DH Series machines are typically used for briquetting hot materials as the rolls can be located farther away from the bearings. Our highest production machine, the DH500 (Screw Feed), is designed for applications that include steel mill by-products, carbon based fuels, inorganic chemicals such as quick lime (CaO), mineral ores, metal oxides, industrial by-products.
