Modelling and optimization of a rotary kiln direct

rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.
