material and energy flows in rotary kiln electric furnace
Oct 25, 2016· An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in therotary kiln-electricfurnace (RKEF) for the smelting offerronickelalloy. One of the measures is to recover the waste heat of exhaust gas from therotary kilnfor preheating and dehydrating the wet laterite ores in therotary dryer
