Tietjen and compound feed
Efficient and reliable feed hammer mills and grinders
Not all animal feeds are equal. The aim of any feed preparation is to ensure better utilisation. Utilisation refers to complete intake and digestion of the feed. The preparation of the feed with a grinder should therefore be geared to different conditions: the intake itself, the crushing in the mouth and the different digestive tracts of the animals. We process grain and other raw materials with precision and energy efficiency with our feed hammer mills. We recognise the requirements and develop grinders for the production of animal feed together with our customers. Take advantage of our experience in feed hammer mills for your success.
How high-quality feed is produced
Grinding plays a key role in the production of high-quality mixed and specialist feed. It has a decisive influence on
- how well nutrients are available
- how stable pellets can be processed later
- and how homogeneous each feed batch turns out to be.
Why particle size and grinding structure are crucial
- A uniform particle size enables digestive enzymes to work more effectively and promotes optimal nutrient absorption in animals.
- Uniform grain size prevents the separation of different components and ensures consistent, reproducible feed quality.
- A suitable grinding structure improves pelletability—it increases stability and abrasion resistance and facilitates handling.
Typical feedstuffs
- Cattle feed, pig feed & horse feed
- Poultry feed & laying hen feed
- Feed pellets
- Grain & green fodder
- Concentrated feed & compound feed
- By-products
- Oilseeds
- Press cake
Modern hammer mills from Tietjen combine quality requirements with high cost-effectiveness. They are designed to process large throughput quantities with consistent results – and with particularly energy-efficient operation. Thanks to variable settings such as screen perforation, speed, or hammer configuration, a precisely defined grist spectrum can be produced that is individually adapted for pigs, poultry, ruminants, or laying hens.
Today, a high degree of flexibility is required in modern mixed feed production. Quick screen changes allow different recipes to be implemented without major interruptions – for example, with 3–4 mm screens for pig, broiler chicken, or cattle feed, or 6–7 mm screens for laying hen feed.
