The Robust Mill for Wet Grinding
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.
