NPK Compound Fertilizer-production line for Best Yields of Crops Three

2018-10-16
 Production Technology of compound fertilizer
 At present, the production technology in the world has been increasingly mature. Our company manufactures and sells complete sets of equipment of compound fertilizer production line, and its yearly output ranges from 10kt to 500kt. with professional installation service and high-quality engineers. We can custom-tailor different production equipment according to your actual demands.
Compound Fertilizer-the Best Yields of Crops(三)
Take the single fertilizer such as urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate, monoammonium phosphate, diammonium phosphate, and coarse whiting, ca) potassium chloride, potassium sulfate as raw material, after grinding to a certain fineness, material in the disc granulator rolling was gathered and granulated by humidifying and heating, in the process of granulating, join a small amount of phosphoric acid and ammonia in a rotary drum granulator, to improve the granulating conditions. composite fertilizer products are processed by drying, sieving and cooling of granulated materials which is also one of the methods widely used in the world. The early United States, India, Japan, Thailand, they all adopt this method -Solid agglomeration process to produce compound fertilizer.

Working Process
1. Horizontal Mixer
It is mainly used to mix raw material. The polypropylene-lined plate or stainless steel plate makes it no material-sticking and stands wear and tear, it has the advantages of compact, easy to operate, stirring evenly, easy to discharge, etc.
2. Rotary drum granulator is a molding machine that can make material into a particular shape. It is one of the key equipment of the compound fertilizer industry, which suitable for cold or hot granulation and mass production for high and low concentration compound fertilizer. The main mode of work is granulation with wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after being humidified. In a certain liquid phase, the rotating movement of the barrel is used to make the extrusion pressure of the material into the ball.
                              
Rotary Cylinder Dryer adopts the means of cylinder marginal transmission, flange connection, directs heat transfer. It is the main equipment in compound fertilizer production, and used for drying granulated fertilizer or raw material. It can make full use of the geothermal energy and get best drying results.
4. Rotary Cooler
Its structure is basically same with rotary dryer. Fertilizers entering from the inlet and cooling air entering from outlet join adversely. The fertilizers of low temperature will be discharged through outlet after transferring the heat to the cooling air. It adopts the design of countercurrent cooling and can decrease pollution and improves the working environment. 
5. Rotary screener is the common equipment in the production of compound fertilizer, which is mainly used for the separation of finished products and reclaimed materials, and can also realize the classification of products, so that the finished products can be evenly classified.
It is the packing machine specially manufactured for quantitative packing of the finished products (compound granular).
