The RKEF process was first applied commercially to treat New Caledonian ore in the late 19th century [3].In general, the literature establishes three stages in the RKEF process [1], [4], [10], [11]: I) drying or preheating in a rotary dryer, II) calcination and partial reduction in a rotary kiln, and III) smelting in an electric arc furnace.The RKEF process is quite mature and …
Key issues governing the performance of rotary kilns are shown schematically in Figure 2. A partially calcined raw meal enters the kiln with a certain flow rate. It is important to develop adequate models to estimate average residence time of solids and variation of bed height within the kiln as a function of solids flow rate, kiln rotational ...
Looking for a traditional 3-base rotary kiln system? You'll get good value from FL's sturdy, flexible, low-maintenance kiln that combines classic technology with well-known performance. …
