DH300 Screw Feed


DH300 Briquetting And Compacting Roll Press

The DH Series briquetting and compacting machines feature rolls located symetrically between two bearings. Making these machines capable of greater roll separating forces. The DH Series machines are typically used for briquetting hot materials as the rolls can be located further away from the bearings. The DH300 (Screw Feed) briquetting and compacting machine applications include, carbon-based fuels, inorganic chemicals such as table salt, mineral ores, industrial by-products and metal powders.
