Introduction For Producing Compound Fertilizer
Compound fertilizer can supply comprehensive nutrient for crops. The production process of compound fertilizer is to combine the main nutrient elements needed for crops (such as N, P, K and other trace elements) by chemical method, that is, gather the nitrogen fertilizer, phosphorus fertilizer, potash fertilizer and other chemicals together and make into particles which are suitable for farming. Then applied into the soil, so that crops can absorb the nutrients they need from soil.
Raw Material For Producing Compound Fertilizer
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:
|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|
Working Principle Of Producing Compound Fertilizer
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).
Raw materials mixing: The mixture of the ingredients should be mixed to improve the uniform fertilizer efficiency of the granules.
Granulation of raw material: The raw material after mixing equably will be sent to granulator (drum granulator, and extruding granulator both can be used).
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.
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.
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.
Finished film: The qualified products are coated to increase the brightness and roundness of granules.
Packaging of finished product: The particles that have been wrapped the film are stored in the ventilated place.
