Pilot Plant Rotary Kilns
Directly heated rotary kiln
| Inner diameter | 400 mm |
| Lenght: | 5 m |
| Solids throughput: | < 700 kg/h |
| Power: | 60...200 kW |
| Product temperature | bis 1200 °C |
| speed of rotation: | 0...10 U/min |
| angle of inclination: | -5°...5° |
The temperatures in the bed , in the wall and the gas are measured radially and axially continuously. At various lengths thermocouples extend to different depths in the rotary tube. Due to a special measuring technology, the measurement data can be recorded continuously. With an probe, which axially extending into the rotary tube, concentrations can be measured in the gas .
Direct current , counter current and batch operation are possible .
Batch rotating drum ( indirectly and directly heated)
| Inner diameter | 23.4 inches |
| Lenght | 17.55 inches |
| Product temperature | to 1472 °F |
| speed of rotation: | 0...10 R/min |
The radial and peripheral temperature curves of the wall , the gas and the bulk bed can be measured. It is being studied in the packed bed of the heat transfer to the free and covered packed bed surface and the heat input.
Batch rotating drum (cold)
On rotary tube segments diameter of 200 to 1000 mm with a glass pane at the front, the movement behavior of various materials will examined.
