Brief description of ammonium sulfate material:
Colorless crystals or white particles. Odorless. Decomposes above 280℃. Solubility in water: 70.6g at 0℃, 103.8g at 100℃. Insoluble in ethanol and acetone. The pH of the 0.1 mol/L aqueous solution is 5.5. The relative density is 1.77. The refractive index is 1.521. Low toxicity, LD50 (rat, oral) 3000mG/kG. It is irritating. Ammonium sulfate is mainly used as fertilizer and is suitable for various soils and crops. It can also be used in textiles, leather, medicine, etc.
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 crop resistance to disasters. It can be used as base fertilizer, top dressing and seed fertilizer, but it can be used for a long time. May cause soil compaction. It can double decomposition reaction with salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and make refractory materials together with boric acid. Adding to the electroplating solution can increase conductivity. It is also a catalyst for the color of food sauces, a nitrogen source for cultivating yeasts in the production of fresh yeasts, dyeing aids for acid dyes, and deliming agents for leather. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important role is to mine rare earths. Mining uses ammonium sulfate as raw material, exchanges the rare earth elements in the ore soil by ion exchange, and then collects the leachate, filters and separates it, and then dried into rare earth ore. The production of 1 ton of rare earth ore is about Need 5 tons of ammonium sulfate.
Working principle of high-efficiency boiling dryer for ammonium sulfate:
After the air is heated and purified, it is introduced from the bottom by the induced draft fan and passes through the perforated mesh plate of the hopper. In the working chamber, fluidization is formed by the action of stirring and negative pressure, the moisture is quickly evaporated and then taken away with the exhaust gas, and the material is quickly dried.
Application scope of high-efficiency boiling dryer:
Machine-made screw extrusion granules, swing granules, wet high-speed mixing granulation granules; drying of wet granules and powder materials in the fields of medicine, food, feed, chemical industry, etc.; large granules, small lumps, viscous lumps and granular materials; when drying konjac, etc. Materials with volume changes.
