DH450 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 DH450 applications include: carbon-based fuels, inorganic chemicals such as quick lime (CaO), mineral ores, metal oxides, and industrial by-products.


  • Solid or segmented roll design for easy roll replacement
  • Vertical-feed design provides either screw-feed or gravity-feed options
  • Pockets available in different shapes and sizes
