All mill diaphragms from Christian Pfeiffer are equipped with plates made out of heat -treated rolled steel. This material quality has a lot of important advantages against the use of plates made out of cast alloy,
The plates have a special slot shape, which assures nearly constant transfer conditions during the entire period of use,
The bolt fastening with conical swages results into a precise fitting to the support structure and allows an efficient use of the plate up to a residual thickness of 8 - 10 mm,
To increase efficiency of the diaphragm lining, we developed a slotted plate construction, which depending on the mill diameter, is divided into two to four rings. The plate rings can be adapted to isolate the area of greatest wear,
Therefore you do not replace the entire lining but only those plate rings that have the greatest wear,
For areas especially exposed to wear, CPB supplies special plates with lifter to increase the lifetime of the slotted and backside plates.
