Well proven Tietjen Quality
Ideal for Pet Food and Aquatic Feed Producers
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.
High Throughput and High Fineness
Your Advantages
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 service life
- 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
- 2 x 4-part screen segments, quick and easy to replace segment by segment
- Reduced distance between beaters and screens prevents clogging of the screens
High level of saftey for personnel and equipment
- Standstill monitoring with door safety device
- Pressure shock resistant and flame-proof
- ATEX design in accordance with Zone 21 (II 2 D) inside and Zone 22 (II 3 D) outside optionally available
