- The intermediate diaphragm divides the tube mill into two grinding chambers with different grinding ball sizes and maintains a material level in the first chamber for optimal pre-grinding,
- The Monobloc® construction for the intermediate diaphragm offers a lot of advantages,
- This construction supports the mill cylinder and prevents large deviations of the ideal round mill shell form resulting from loads of up to 300 mt of ball charge,
- Additionally, Christian Pfeiffer developed the "floating fixation" which considerably reduces interactive load influences between diaphragm structure and mill cylinder,
- Depending on the mill diameter, the slotted and backside plates are divided into two to four rings. The plate rings can be adapted to isolate the area of greatest wear according to experience,
- Each diaphragm centre can be adapted to the individual ball charge filling ratio,
- Through the regulation of the material flow control system and limitation of the largest grain size, the material remains in the first grinding chamber till its optimal pre-grinding,
- The latest development from Christian Pfeiffer is the material flow control system of the 4th generation.
