OPTIMAL GRINDING OF CEREALS AND FOODSTUFFS

Weizen und Zuckerruebe

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.

Efficient Wet Grinding
Your Advantages
