Based on the characteristics of nickel sulfate and its hydrate,a fixed-fluidized bed drying process integrating drying and cooling was introduced,which was combined with dust treatment process such as tail gas recirculation to meet the requirements of energy saving and environmental protection.The processing capacity of the system can reach more than 16 t/h,the processing capacity of the exhaust system can be reduced by up to 45%,and 7000 cal can be saved per ton of dry materials.
