The classic when it comes to wet grinding
OPTIMAL GRINDING OF CEREALS AND FOODSTUFFS
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.
