Traditional new vanadium powder production technology and equipment of production powder ammonium vanadate, vanadium's main production methods: is the use of rotary kiln. Product quality is stable, and there was burning, does not run continuously, high energy consumption, environment and pollution by waste seriously. In response to the user's requirements, our company has developed an applied to roasting of vanadium powder production line. The joint dynamics of drying and calcining process route. Equipment to produce powders of vanadium products of stable quality.  Flash drying and calcining furnaces with energy-saving, environmental and pollution-free, high recycling efficiency, covering an area of small, high degree of automation. Work principle: will by dynamic calcined furnace calcined material Hou production of exhaust entered Republika de drying machine within, by sent material machine will moisture 20~30% of filter pie shaped vanadium acid ammonium into drying machine, by scattered drying formed powder, again into dynamic calcined furnace within, by coal-fired, and gas or gas produced of hot air entered calcined furnace within, with into furnace within and powder of vanadium acid ammonium for mixed heat transfer, by 500~900℃ hot air of heating, by several seconds quickly decomposition for powder vanadium products,  After decomposition of the powders of vanadium products by trap and trap into the silos. Features: 1. fast decomposition temperature uniformity, can achieve a stable quality of vanadium powder production.  2. to the cake of ammonium vanadate on vanadium powder powder production in one system. 3. environmental pollution-free, covers an area of small, easy maintenance operations, a high degree of automation. 4. continuous operation. 5. recovery >99%6. energy-saving. Technical specifications: in series within a single set of vanadium powder output of 1000, 2000, 3,000, 5,000 tons/year manufacturer: Weiyuan, Sichuan iron and steel company
