Weizen und Maiskerne
Optimum grinding in all areas

Maximum throughput capacity for use in ultra-fine grinding

Weizen und Maiskerne

The GD hammer mill can be used in particular for the fine grinding of pet food and fish feed as well as for grinding in compound feed production, the ethanol industry and in the timber industry. Sophisticated design for efficient grinding of demanding recipes and products. The special 6-axis rotor design with quick-change beater carrier system and optimised beater configuration guarantees maximum material contact for the efficient production of fine and coarser feed qualities.

Advantages of the large capacity grinder GD

Prallbahnen Rotor Träger-Wechselsystem Pneumatische-Umlenkung Lagertemperatur-Überwachung

Efficient Grinding at High Capacities

  • Optimised impact zone with hardened impact plates on both sides of the inlet
  • Universal use from fine to coarse grinding possible
  • Large grinding chamber for high capacities
  • High energy efficiency due to special rotor design
  • Suitable for the use of all common screen perforations
  • Variable grist spectrum by changing 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 beater change due to beater frame system, beaters can be changed 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 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
