The classic for medium throughputs
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.
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
- Rotor design also suitable for large pieces of material that are difficult to grind
- Suitable for the use of all common screen sizes
- 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
High Availability with Low Downtimes
- Quick and easy change of beaters due to beater changing device (option)
- Rotor with short run-down time < 6 min without brake
- Wide-opening doors allow easy and quick access to the machine interior
- 2-part screen segments without frame, easy and quick to change segment by segment
High Safety of Personnel and Plant
- Standstill monitoring with door safety device
- Pressure shock resistant and flameproof design (0.4 bar)
- ATEX design according to zone 21 (II 2 D) inside and zone 22 (II 3 D) outside optionally possible
