The process of compound fertilizer granulation equipment is mainly to screen, magnetic separation, granulation and drying the fermented organic waste with a moisture content of about 30% -35% to prepare round Organic fertilizer. Adding functional bacteria can produce biological Manure, and adding nitrogen, phosphorus and potassium (the total nutrient content is less than 15%) can produce organic and inorganic fertilizer.
Complete compound fertilizer production line process
1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, calcium superphosphate), Potassium chloride (Potassium sulfate) and other raw materials shall be prepared in a certain proportion (according to market demand and soil testing results in various regions).
2. Mixing of raw materials: Mix the prepared raw materials evenly to improve the overall uniformity of the fertilizer particles.
3. Raw material granulation: The evenly stirred raw materials are fed into a composite fertilizer granulator for granulation (either a drum granulator or an extrusion granulator can be used).
4. 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.
5. 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.
6. Particle grading: Grading the cooled particles, crushing and re granulating the unqualified particles, and screening out the qualified products.
7. Finished film: Coating qualified products to increase the brightness and roundness of particles.
8. Finished product packaging: Bag the coated particles, also known as finished products, and store them in a ventilated place.
The compound fertilizer production line has low investment, fast efficiency, and good economic benefits. The complete equipment process layout is compact, scientific and reasonable, and technologically advanced. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, etc., with high product granulation rate. It can produce compound fertilizers of various concentrations and types (including Manure, inorganic fertilizer, biological fertilizer, magnetized fertilizer, 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.
