The all-rounder
THE UNIVERSAL MILL FOR COARSE GRINDING
The Hammer Mill VL is the universal mill for coarse grinding in compound feed, as well as fine grinding, in pet food and aqua feed production. Further areas of application for this all-rounder include the grinding of chemical components, salts, spices, and natural products such as wood.
Coarse- and fine grinding
Advantages of the High Speed Mill VL
Efficient Grinding of a Wide Range of Products
- Optimised impact zone with hardened impact plates on both sides of the inlet
- Universal use from fine to coarse grinding possible
- Suitable for the use of all common screen perforations
- Variable grist spectrum by adjusting the beater circumferential speed (when using a frequency converter), the screen perforation and the beater configuration
Reliable Operation and Long Service Life
- Robust welded steel construction for continuous industrial operation (24/7)
- Grinding chamber equipped with wear elements to protect the housing, easy to change
- Durable, optimised rotor design, dynamically balanced, operation in both directions of rotation
- To protect the screens: foreign body catch trap for impurities inside the grinding chamber
