GP 400 M with chip turner and feed screw
Economical briquetting technology, reliable and powerful

The GROSS briquetting presses with their flexible application possibilities can produce briquettes from all kinds of wood materials with low bulk density, for example from sawdust, chipping chips or shavings. Thanks to sophisticated technology, these materials can be economically converted into compact briquettes and achieve an enormous volume reduction. Thanks to efficient equipment, the GROSS briquetting presses can also be used optimally in the area of the briquetting of paper and paper dust, polystyrene, light metal or similar materials.
