DH400 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. The DH400 briquetting and compacting machine is ideal for briquetting and compaction applications that include carbon-based fuels, inorganic chemicals such as quick lime (CaO), mineral ores, industrial by-products, salt and metal powders.
