For High Flexibility with Fully Automatic Screen Change LARGE CHAMBER HAMMER MILL GDX The large chamber hammer mill GDX is particularly suitable for the production of compound feed where the feed structure requirements change frequently. Due to the design as a large chamber mill, high throughput rates are achieved. A special feature is the fully automatic screen change during idling at the push of a button from the control room. Together with an FI-controlled motor, this results in maximum flexibility with regard to the grist spectrum. Your Advantages Efficient Grinding, High Capacities and Maximum Flexibility • To protect the screens: foreign body catch trap for impurities inside the grinding chamber • Optimised impact zone with hardened impact plates on both sides of the inlet High Availability with Low Downtimes • Large grinding chamber for high capacities • Fully automatic change of different screen perforations during idling • 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 • Quick and easy change of beaters due to beater frame system, beaters can be changed outside the mill • Variable grist spectrum by adjusting the beater circumferential speed (when using a frequency converter), the screen perforation and the beater configuration • 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 Reliable Operation and Long Service Life • Wide-opening doors allow easy and quick access to the machine interior • Robust welded steel construction for continuous industrial operation (24/7) High Safety of Personnel and Plant • Grinding chamber equipped with wear elements to protect the housing, easy to change • Standstill monitoring with door safety device • Pressure shock resistant and flameproof design (0.4 bar) • Durable, optimised rotor design, dynamically balanced, operation in both directions of rotation • ATEX design according to zone 21 (II 2 D) inside and zone 22 (II 3 D) outside optionally possible Technical Details Type Grinding chamber diameter (mm) Grinding chamber area (m2) Speed with frequency converter 34-60 Hz Dimensions and weight Length* x width x height (approx. mm) *depending on motor size Weight without motor (approx. kg) Drive Motor size (kW) Tietjen Verfahrenstechnik GmbH Vor der Horst 6, D-25485 Hemdingen
