Well proven Tietjen Quality
The hammer mills of the FD Pro series are optimized for the fine grinding of fat and protein-rich recipes. Their sizes are tailored to common extruder capacities and can even serve the latest extruder lines with just one machine. The mills feature a special screen holder and seal to limit the maximum particle size. The beaters can be changed quickly and easily thanks to the proven Tietjen beater frame system.
Take Advantage of These Benefits
High Throughput and High Fineness
- Energy-efficient fine grinding of fish feed, pet food, and other products
- Optimized impact zone with hardened impact plates
- Extension of the impact zone for higher fineness and a narrower grist spectrum possible with impact plates
- Special sealing of the screens so that no coarse off spec particles enter the product
- Variable grist spectrum by changing the beater speed (when using a frequency converter), the screen perforation and the beater configuration
Reliable Operation and Long Durability
- Robust welded steel construction
- Grinding chamber equipped with wear elements to protect the housing, easy to replace
- Durable, optimized rotor design, dynamically balanced, operation in both directions of rotation
- Foreign matter catch trap for impurities
High Availability with Low Downtimes
- Quick and easy beater change thanks to beater frame system, beaters can be replaced outside the mill
- Solid screen frames and screen fixing with toggle clamps – easy and reliable to operate
- Rotor with short run-down time < 6 min without brake
- Sliding doors: quick and easy access to the machine interior
