Mechanism Of Rotary Kiln Pdf

Abstract this paper deals with the mathematical modelling of a rotary kiln which is used for the recycling of aluminium waste this model is mainly based on the coupling between • a bed model describing the processes occurring within the bed of aluminium waste flowing inside the kiln • a kiln model describing heat transfer within the kiln itself • a gas model.
