Ammonium Metatungstate Production Equipment

Ammonium metatungstate production equipment according to the different stages of production and different methods may be variety, such as pyrolysis method of AMT production, a reactor, rotary kiln, high-speed centrifugal spray drying equipment or spray atomization drying equipment may be used; In addition, other pyrolysis equipments include microwave oven, plate multiple hearth furnace and tubular multiple hearth furnace. The direct recovery AMT can be more than 95% when using tubular multiple hearth furnace.

Ammonium metatungstate produced by ion exchange method will probably use ion exchange resin, crystallizer, or spray dryer.

Alkali decomposition furnace is mainly used for decomposing tungsten ore during the preparation of AMT 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 in the APT preparation.

Ion exchange colum is used for removal of S, Mo, P, As, Ca, Cu and Sn and other impurities. Co-current deionization refers to the original downflow process where both input water and regeneration chemicals enter at the top of an ion exchange column and exit at the bottom. Co-current operating costs are comparatively higher than counter-current deionization because of the additional usage of regenerants. Because regenerant chemicals are dilute when they encounter the bottom or finishing resins in an ion exchange column, the product quality is lower than a similarly sized counter-flow column. Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals.
