Ammonium metatungstate spray drying tower belongs to the spray equipments of ammonium metatungstate production, which is the most widely used of liquid forming process and drying industry. Spray-drying tower is suitable for preparing powder, granular solid product from liquid raw material with forms of suspoemulsions, solution, emulsion, and paste. Thus, when the finished product particle size distribution, residual moisture content, bulk density and particle shape are in line with the precision standard, the spray drying tower is supposed to be an ideal drying process.

Principle of ammonium metatungstate spray drying tower is that the air goes into the top dryer’ air distributor after filtered and heated, then the hot air will uniformly go into the drying room in the spiral. AMT feed solution through the high-speed centrifugal atomizer (rotary) at the top of the tower to be sprayed into the extremely fine mist liquid beads AMT, and dried AMT will come into being in a very short time when it in contacts with the stream of hot air. Then, ammonium metatungstate is exported continuously from the bottom of the spray drying tower and the cyclone, and the exhaust gases are vented by the fan.

Extended reading:
Spray drying tower is the equipment which can be used in drying biological pesticide, medicine and food microorganism, with the max evaporation rate of 10 kg/h, max gas drying rate of 150 kg/h; the main function of a spray drying tower is to dry the materials in solution state in it and then discharge in form of solid. There are 6 properties of a spray drying tower which show bellows:
1. The fast drying speed within seconds to finish;
2. Suitable for the heat-sensitive materials;
3. Widely apply in most of products with very huge difference;
4. The outlet product has excellent dispersion, fluidity and solubility;
5. Sample producing process and easy to operate and control;
6. The part which in contact with material is using stainless steel to protect raw material not to be polluted and extend the service life of the equipment.
