The specialist for fine foods
Ideal for sophisticated recipes and products
The hammer mill FD is a further development of our proven large chamber mills that has been specially optimised for fine grinding in the 400-800 μm range. It is therefore particularly suitable for demanding recipes in the pet food and fish feed sectors, but also for similar requirements in other products, such as the production of wood flour.
Efficient grinding of demanding recipes
Advantages of the large capacity grinder FD
Efficient Grinding for High Fineness Requirements
- Optimised impact zone with hardened impact plates on both sides of the inlet
- Extension of the impact area for higher finenesses and narrower grist spectrum possible with impact plates made of Hardox
- Stabilisation of the fine and thin screens by a support cage
- Special sealing of the screens so that no coarse off-spec grain gets into the product
- 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 frame system, beaters can be exchanged outside the mill
- With a second set of beater frames, the machine is immediately ready for use again
- Rotor with short run-down time < 6 min without brake
- Wide-opening doors allow easy and quick access to the machine interior
- 4-part screen segments (max. 2 mm sheet thickness) 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
