The classic when it comes to wet grinding
OPTIMAL GRINDING OF CEREALS AND FOODSTUFFS

Liquid quantities of e.g. water and additives e.g. enzymes are continuously added to the grinding process in dosed quantities through connection openings in the product inlet area. The product is then ready for pumping after grinding.
Efficient Wet Grinding
Your Advantages
Efficient Wet Grinding
- Optimised impact zone with hardened impact plates on both sides of the inlet
- Universal use from fine to coarse grinding possible
- Injection nozzles for liquid addition in the inlet area
- Suitable for the use of all common screen perforations
- 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
- Stainless steel design of rotor and housing possible
High Availability with Low Downtimes
- Quick and easy change of beaters due to beater changing device (option)
- Rotor with short run-down time < 6 min without brake
- Large hinged or sliding doors allow easy and quick access to the machine interior
- 2-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
