Tungstic Acid Producing Equipment

Tungstic acid producing equipment according to the industrial production process will have a series of equipments, because industrial production of tungstic acid mainly through alkali decomposition, filter, ion exchange, dry and reduction and other processes, thus to need different devices, such as alkali decomposition furnace, plate and frame filter press, ion exchange column, tungsten acid dryer, etc.

Alkali decomposition furnace is mainly used for decomposing tungsten ore during the preparation of tungstic acid to dissolve tungsten into a solution. A plate and frame filter press is the most fundamental design, and many now refer it as a "membrane filter plate". This type of filter press consists of many plates and frames assembled alternately with the supports of a pair of rails. It is used for the impurity removal process of sodium tungstate for preparing high purity sodium tungstate during the tungstic acid preparation.

Ion exchange column is also called as mixed bed, which is the cylindrical pressure vessel used for ion exchange reaction, and to remove a series of impurities of S, Mo, P, As, Ca, Cu and Sn in the process of tungstic acid production. Tungstic acid dryer is the equipment for drying tungstic acid, the dryer is a drying machine to remove water from some specific material by heating, and thus to meet the application and further processing requirements.
