Compound Fertilizer Spray Dryer

Compound fertilizer is the most widely used process in liquid shaping technology. It is suitable for producing powder and granules solid products from solution, emulsion, soliquoid, and pumpable paste materials. Therefore, when the particle size, final moisture, bulk density and granules shape meet the accurate standard, centrifugal spray drying is a ideal drying process.

Description

Description

The fertilizer centrifugal spray dryer is equipped with a centrifugal atomizer and is currently one of the most widely used dryers in industrial production. The material liquid is added to the high-speed rotating atomization plate, and the liquid is thrown into mist droplets by centrifugal force and then dried in the drying chamber.

Working Principle

The feed pump pumps the solution water reducing agent to the high-speed centrifugal atomizer in the center of the drying tower, and uses the centrifugal force generated by the high-speed rotation to atomize the feed liquid into fine droplets. The hot air heated by the heat source enters the drying tower after being reasonably distributed by the air distributor. The mist and hot air are fully mixed in the drying tower, and the heat and mass are exchanged quickly, and they are dried into powder products in a very short time. Products with larger particle diameters are discharged from the bottom of the drying tower, and products with smaller particle diameters follow. The hot air enters the cyclone dust collector, the separated products are discharged through the discharge valve, and the tail gas containing a small amount of dust is emptied after being dusted by the water dust collector.

Characteristics:

1. High operational flexibility on non-adhesive or low-adhesive liquid materials.

2. Simple structure of the spray nozzle, easily used and maintained.

3. Less power consumption, low cost.

4. The hollow spherical product with big particles, good mobility and solubility.

5. Can be used to spray-cooling granulation process, such as paraffin, grease particles, special resins, etc.

Applicable Materials

Fertilizer Powder

Compound fertilizers, which contain N, P, and K, can often be produced by mixing straight fertilizers. In some cases, chemical reactions occur between the two or more components. For example, monoammonium and diammonium phosphates, which provide plants with both N and P, are produced by neutralizing phosphoric acid (from phosphate rock) and ammonia

Food: Amino acid, vitamin, egg powder, bone powder, protein, milk powder, blood powder, soy sauce powder, coffee, tea powder, glucose, pentadiene carboxylic acid, pectin, flavours, vegetable juice, yeast, starch, etc.

Ceramic: Alumina, zirconia, magnesium oxide, Titania, pottery clay, china clay, all kinds of magnetic porcelain and metal-oxides, etc.

Chemical: Aluminum polychloride, disperse dyes, reactive dyes, organic catalyzer, white carbon black, washing powder, zinc sulfate, silica, sodium metasilicate, potassium fluoride, calcium carbonate, potassium sulfate, inorganic catalyzer, wasted liquid, etc.
