From coarse to fine
PERFECT FOR THE PRODUCTION OF COMPOUND FEED, PET FOOD AND FISH FEED
Specifically designed for efficient grinding: The special 6-axis rotor design plus optimized beater configuration in combination with high beater tip speed guarantees maximum material contact for the efficient production of the finest feed as well as coarser products. The LDE Series comprises three sizes with a drive-power range beetween 55 and 200 kW.
Versatile ammer mill with easy screen change
Your Advantages
Efficient Grinding and High Flexibility
- Optimised impact zone with hardened impact plates on both sides of the inlet
- Universal use from fine to coarse grinding possible
- Suitable for the use of all common screen perforations
- Quick screen change allows a selective structure change of the ground material in just a few minutes
- Variable grist spectrum by adjusting 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
