Special high-efficiency boiling dryer for ammonium sulfate

Brief introduction of ammonium sulfate

Colorless crystals or white particles. Odorless. Decomposes above 280°C. Solubility in water: 70.6g at 0°C, 103.8g at 100°C. Insoluble in ethanol and acetone. The pH of the 0.1 mol/L aqueous solution is 5.5. The relative density is 1.77. Refractive index 1.521. Low toxicity, median lethal dose (rat, oral) 3000mG/kG. irritating. Ammonium sulfate is mainly used as a fertilizer and is suitable for various soils and crops. It can also be used in textile, leather, medicine and so on.

The role and use of ammonium sulfate materials

An excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters. It can be used as base fertilizer, top dressing and seed fertilizer, but long-term use May cause soil compaction. It can undergo metathesis reaction with table salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and produce refractory materials together with boric acid. Adding to the electroplating solution can increase conductivity. It is also a catalyst for food sauce color, a nitrogen source for cultivating yeast in the production of fresh yeast, a dyeing aid for acid dyes, and a deliming agent for leather. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important role is to mine rare earths. Ammonium sulfate is used as raw material for mining, and the rare earth elements in the ore are exchanged by ion exchange. The leaching solution is collected and simply filtered and separated, and then dried into rare earth ore. Each ton of rare earth ore produced is about 5 tons of ammonium sulfate are required.

The working principle of the special high-efficiency boiling dryer for ammonium sulfate

After the air is heated and purified, it is introduced from the lower part by the induced draft fan and passes through the mesh plate of the hopper. In the working room, the fluidization is formed by stirring and negative pressure, and the water evaporates quickly and then is carried away with the exhaust gas, and the material is quickly dried.

Scope of application of high-efficiency boiling dryer

Mechanism screw extrusion granules, rocking granules, wet high-speed mixing granulation granules; drying of wet granules and powdery materials in the fields of medicine, food, feed, chemical industry, etc.; large granules, small blocks, sticky block granules; konjac, etc. Materials that vary in volume.
