Hammer Mill GD
The powerhouse for maximum performance
- Universal mill for a wide range of applications
- Ideal for medium to high throughput
- Quick and easy screen change during standstill
- Quick beater change thanks to rotor with beater frame
Recommended for
Possible for
For High Throughput Rates
The hammer mill GD is suitable for use in compound feed production, the ethanol industry, the wood processing industry and for grinding a wide range of other products. Due to the design as a large chamber mill with a diameter of the grinding chamber of 1200 mm and with a width of up to 1250 mm, high throughput rates are achieved.
Take Advantage of These Benefits
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
Hardened impact zone
