The High Temperature Pressurized Shaft Kiln
- The pressurized shaft kiln has been invented by the RCE inRadenthein / Austria in the Mid-1970s.
- The first application, a 50tpd kiln is s till in operation todayfor the production of Alumina-Spinel.
- Around 50 installations worldwide

High TemperatureShaft Kiln
A new process for refractory grade bauxiteproduction
Dr.Christo h Be er, Pol sius AG
- Low energy consumption compared to other kilntypes for s intering
- High flexibility due to variable number of burnersand burner levels
- High and homogeneous product quality by even
heat distribution due to multiple burner lances
- Highest burning temperature (> 2200C ) due to
counter current operation
