Technical details
  • Robust welded steel construction, symmetrical housing for operation in both directions of rotation.
  • Grinding chamber equipped with wear elements to protect the housing walls, easy to replace
  • Armored inlet flap with position switch for change of direction of rotation
  • Optimized impact zone with armored impact plates on both sides of the inlet for efficient size reduction
  • Easy expansion of the impact zone via insertable impact elements
  • Debris catcher pocket for contaminants inside the grinding chamber (e.g. to protect the screens)
  • Durable, optimized rotor design, dynamically balanced, run-down time < 6 minutes without brake
  • Beater carrier system (cassette change): easy, quick beater change in a few minutes
  • Wide opening doors allow easy access to the grinding chamber
  • Large grinding chamber, 4-part sieve segments without frame, (max. thickness 2.0 mm), easily and quickly changed segment by segment
  • Mill and motor unit can be separated, easier installation especially in confined spaces
  • Tested and certified in pressure shock resistant and flameproof design (0.4 bar)
  • Variable particle size spectrum via variable beater circumferential speed (when using a frequency converter), sieve perforation and
  • beater configuration; depending on requirements.

fish food
The specialist for fine foods

Ideal for sophisticated recipes and products

fish food

The hammer mill FD was specially designed for the requirements of fine grinding. Sophisticated design for efficient grinding of demanding recipes and products: The special 6-axis rotor design with quick-change beater carrier system, as well as optimised beater configuration, guarantees maximum material contact for the efficient production of fine feed qualities.
As an option, the FD also offers the variability to easily enlarge the impact zone and thus optimise the fineness and grinding performance depending on the recipe and requirements.

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
