Is The Orientation Of A Rotary Kiln Important

Deposition And Screeding After Rotary Kiln Discharge

201932 Summary. Discharge of pellets from rotary kiln was studied using the Discrete Element Method. The task was to compare four scenarios different ways of diffusing pellet stream at discharge regarding their deposition pattern and load on the screed wall, which serves as leveling mechanism to assure even distribution of pellets across the moving cooler.
