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.

The specialist for fine materials

Ideal for highly demanding recipes and products

fish food

The large chamber mill FD was designed specifically for the requirements of fine grinding. Sophisticated design for the efficient grinding of demanding recipes and products: The special 6-axis rotor design with quick-change beater frame system, as well as optimised beater configuration, delivers maximum material contact for the efficient production of fine feed qualities.
The FD also offers the option of simply enlarging the baffle zone, thereby optimising the fineness and grinding capacity depending on the recipe and requirements.
