The classic for medium throughputs

Robust machine for use in ultra-fine grinding

Weizen- und Saegespaehne

The Hammer Mill VDK is designed for fine grinding in pet food and aqua feed production, as well as for coarse grinding, in the feed-milling, ethanol and wood industries. Specifically designed for efficient grinding for challenging recipes and products: The special 6-axis rotor design plus optimized beater configuration in combination with high beater tip speed guarantees maximum material contact for the efficient production of the finest feed as well as coarser products.

The use of waste wood as a substitute fuel in coal-fired power plants is gaining enormous importance in the energy transition. VDK Hammermühle plays an important role in this context. You can find out more in our article Waste wood as a substitute fuel and alternative to coal.
