The process flow of the complete set of nitrogen phosphorus potassium compound fertilizer equipment can usually be divided into: raw material batching, raw material stirring, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and final product packaging.
The complete set of equipment for nitrogen phosphorus potassium compound fertilizer has low investment, fast effectiveness, and good economic benefits. The entire nitrogen phosphorus potassium compound fertilizer production line has a compact layout, scientific and reasonable process, and advanced technology. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance.
The complete set of equipment for nitrogen phosphorus potassium compound fertilizer has a wide range of raw material adaptability, suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, etc., with high product granulation rate. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). Especially for the granulation of rare earth and ammonium bicarbonate series compound fertilizers, it fills the domestic gap and ranks at the leading level in China.
Complete production line process of nitrogen phosphorus potassium compound fertilizer
- Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, superphosphate), potassium chloride (potassium sulfate) and other raw materials are prepared in a certain proportion (based on market demand and soil testing results in various regions).
- Mixing of raw materials: Mix the prepared raw materials evenly to improve the overall uniformity of the fertilizer particles.
- Raw material granulation: The evenly stirred raw material is fed into a granulator for granulation (either a drum granulator or an extrusion granulator can be used).
- Particle drying: The particles made by the granulator are fed into the dryer to dry the moisture contained in the particles, increasing their strength and facilitating storage.
- Particle cooling: The dried fertilizer particles have a high temperature and are prone to clumping. After cooling, they are easy to pack, store, and transport.
- Particle grading: Grading the cooled particles, crushing and re granulating the unqualified particles, and screening out the qualified products.
- Finished film: Coating qualified products to increase the brightness and roundness of particles.
- Finished product packaging: Bag the coated particles, also known as finished products, and store them in a ventilated place.
