| Rotary calciner |
|
For reduction of oxydes powders in metallic powders.
The rotary calciner systems are optimally utilized for the processing of fine (0.8 to 100 µm) inorganic powders.
A patented rotary seal enables continuous operation in controlled process atmospheres (H2, N2, Ar, He, CO, CO2) as well as complete dust tightness. Systems are available with fully integrated weight controlled feeding, process gas recycling, dust collection, and state of the art control and supervisory systems. The range of system specifications is: |
