The new cryolite drying and calcining equipment independently developed by Jiaozuo City, Henan Province, has been successfully applied in industrialization in Jiaozuo City Duofuo Chemical Co., Ltd.
At present, the drying of cryolite is mainly based on rotary kiln. This equipment is bulky, has high running cost, unstable product quality and low yield. Jiaozuo City Dede Chemical Machinery Co., Ltd. has successfully developed a new type of dry calcining equipment based on independent innovation. The equipment shows the following characteristics in industrial production: the product quality is stable and reliable, the superior grade rate is over 99%; the equipment can reuse heat energy, the direct energy consumption per ton of product is reduced by 150 yuan; the operating cost of the equipment is reduced, and the worker operating intensity is reduced. The difficulty is also greatly reduced. The equipment can also be applied to aluminum fluoride, aluminum chloride, kaolin and other products, and has a good promotion prospect in the inorganic chemical drying and calcining industry in China.
