The classic when it comes to wet grinding

Optimal grinding of cereals and foodstuffs

Weizen und Zuckerruebe

The NDK hammer mill has been specially designed for the wet grinding of cereals, potatoes, fruits, organic waste, with added liquids. Liquid quantities of e.g. water and additives e.g. enzymes are continuously added to the grinding process in dosed quantities through connection openings in the product inlet area.  The product is then ready for pumping after grinding.
