Weizen und Maiskerne

The solution for frequently changing requirements

Maximum flexibility with different structures
Weizen und Maiskerne
The Hammer Mill GDX is designed for grinding compound feed, with frequently changing requirements, in the feed structure.
The fully automatic screen change also makes it possible to quickly change between two screen perforations by mouse click, and while the machine is running. Together with a frequency converter (FC) controlled drive, this results in a maximum of variability in terms of the grain spectrum.

Your Advantages
Rotor GDX Pneumatische Umlenkung

Efficient Grinding, High Capacities and Maximum Flexibility

  • Optimised impact zone with hardened impact plates on both sides of the inlet
  • Large grinding chamber for high capacities
  • High energy efficiency due to special rotor design
  • Fully automatic screen change allows a selective change in the structure of the ground material in just a few seconds
  • 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

  • Fully automatic change of different screen perforations during idling
  • Quick and easy change of beaters 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

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
