15-15-15 NPK Fertilizer Production Line With Roller Press Granulator
Introduction of NPK Fertilizer Production Line
Compound NPK fertilizer production line process can be divided into: raw ingredients, mixed raw material, granulated material, drying the granules, particles were cooled, particles are classified, and finished product packaging film packaging.
NPK fertilizer production line is widely used in the production of compound fertilizer production capacity 5000-20 tons / year. May NPK, NP, ANP, DAP, MAP, CAN, SSP fertilizer and other materials into granules granulated in a production line.
Raw Material For NPK Compound Fertilizer Making Production Line
Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:
Nitrogen | Phosphorus | Potassium | |
Calcium nitrate | urea | Single superphosphate | Kainit |
Ammonium bicarbonate | Ammonium chloride | Rock phosphate | Potassium chloride |
Nitrate of soda | Ammonium sulphate nitrate | Dicalcium phosphate | Potassium sulphate |
Ammonium sulphate | Ammonium nitrate | Triple superphosphate | Potassium nitrate |
Characteristics Of NPK Compound Fertilizer Making Production Line
The small compound fertilizer production line investment, quick, good economic returns. The entire process compact equipment, scientific and advanced. Saving energy, no waste discharge, stable, reliable operation and easy maintenance. Wide adaptability of raw materials, the machine is suitable for fertilizer, pharmaceuticals, chemicals, feed and other granulation, granulation rate. The machine can produce a variety of different concentrations, different types of fertilizer (including organic fertilizer, inorganic fertilizer, fertilizer, fertilizer and other magnetic). Especially ammonium fertilizer potash feldspar carbide particles fill the gaps, the leading domestic.
The Process of NPK Fertilizer Production Line
1, ingredients: urea, ammonium nitrate, ammonium chloride, ammonium
sulfate, ammonium phosphate (monoammonium phosphate, diammonium
phosphate, a crude white powder, CA), potassium chloride, potassium
sulfate, etc. raw material proportion ratio (based on market demand
And the surrounding soil of the test results).
2, the mixed raw material: mixing ingredients to be mixed, to
improve uniformity of the fertilizer particles.
3, granulated material: raw materials are mixed uniformly into the
granulator (drum granulator, extrusion granulator available).
4, granulating drying: granulating put into a drier, drying the
particles in the water, increasing the granulation strength, easier
to store.
5, the cooling granulation: After drying the granulation
temperature is too high, agglomeration easily granulated. After
cooling to facilitate storage and transport bag.
6, particles are classified: the cooling of the cooled classifying
particles: particles pulverized and then granulated unqualified and
qualified products are screened out.
7, the finished film: coated qualified products, and increase the
brightness of the roundness of the particle.
8, the finished packaging: wrap film stored in ventilation
particles.
Features of NPK Fertilizer Production Line
