The hammer mill series GDx is a 1.500 rpm mill which is designed for extreme capacities. Only the GD8 and GD9 are commonly used machines in breweries, the GD10 is only for exceptionally large batches and only used in very high capacity breweries.

The mills are standard equipped with feeder for mill load control (with automatically cleaning magnet), expansion bin with grist extraction system, manual sampling unit and filter/ventilator. Explosion venting and barriers at inlet and outlet support full ATEX compliance.
