8 - 10 TON / HOUR DZJ SERIES DEMAND VOLTAGE NPK FERTILIZER PRODUCTION LINE

8-10T/H Fertilizer NPK 15-15-15 Compound Fertilizer Production Line

 
Introduction of NPK Fertilizer Production Line

NPK Compound fertilizer production line is widely applied to produce compound fertilizer and the capacity ranges from 5000-200,000 tons/year. The process flow of the compound fertilizer production line can be divided into: raw material ingredients, raw material mixing, raw material granulation, particle drying, granular cooling, particle grading, finished packaging film and final product packaging.

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:

Characteristics Of NPK Compound Fertilizer Making Production Line

The whole equipment process is compact, scientific and advanced. Energy saving and consumption reducing, no waste removal, stable operation, reliable running, convenient maintenance. The adaptability of raw materials is wide, and the machine is suitable for the granulation of compound fertilizer, medicine, chemical industry, feed, etc., and the granulation rate is high. 
 

The Process of NPK Fertilizer Production Line

1. Raw material ingredients: Urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, and coarse whiting, ca), potassium chloride, potassium sulfate and other raw materials are matched in proportion (according to the market demand and the around soil of test results).
2. Raw materials mixing: The mixture of the ingredients should be mixed to improve the uniform fertilizer efficiency of the granules.
3. Granulation of raw material: The raw material after mixing equably will be sent to granulator (drum granulator, and extruding granulator both can be used).
4. Granulation drying: put the granulation into the dryer, and the moisture in the granules will be dried, so that the granulation strength is increased and is easier to store.
5. Granulation cooling: After drying, the granulation’s temperature is too high and the granulation is easy to lump. While after cooling, it is easy to bagging to save and transport.
6. Particle classification: the cooling particles that have been cooled will be graded: the unqualified particles will be crushed and regranulated, and the qualified products will be sift out.
7. Finished film: The qualified products are coated to increase the brightness and roundness of granules.
8. Packaging of finished product: The particles that have been wrapped the film are stored in the ventilated place.

Working Principle of NPK Fertilizer Production Line

1. Granulation drying: put the granulation into the dryer, and the moisture in the granules will be dried, so that the granulation strength is increased and is easier to store.
2. Granulation cooling: After drying, the granulation’s temperature is too high and the granulation is easy to lump. While after cooling, it is easy to bagging to save and transport.
3. Particle classification: the cooling particles that have been cooled will be graded: the unqualified particles will be crushed and regranulated, and the qualified products will be sift out.

4. Raw material ingredients: Urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, and coarse whiting, ca), potassium chloride, potassium sulfate and other raw materials are matched in proportion (according to the market demand and the around soil of test results).
