Application of Compound Fertilizer Production Line in NPK Compound Fertilizer Plant

Characteristics of compound fertilizer production line products:
This equipment has low investment, fast effectiveness, and good economic benefits. The layout of the complete equipment process is compact, scientifically reasonable, and technologically advanced. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance. 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 carbonate series compound fertilizers.

The process flow of compound fertilizer production line can usually be divided into: raw material batching, raw material stirring, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and finished product packaging.

1. 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 proportion (according to market demand and soil testing results in different regions).
2. Raw material mixing: The compound fertilizer equipment will mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles.
3. Raw material granulation: The evenly mixed raw materials are fed into a 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 inside 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 classification: The compound fertilizer production equipment classifies the cooled particles, and the unqualified particles are crushed and re granulated to screen out the qualified products.
7. Finished film: Coating qualified products to increase the brightness and roundness of particles.
8. Finished product packaging: Bag the processed particles, which are the finished products, and store them in a ventilated place.

Characteristics of compound fertilizer equipment:
1. The applicability of raw materials and their wide applicability to the direct granulation of crude fiber organic waste with a moisture content of about 30%, such as fermented livestock and poultry manure, sugar factory filter sludge, urban sludge, papermaking sludge, distiller's grains, straw, and peat, can produce pure organic fertilizer, organic inorganic fertilizer, and bio organic fertilizer with spherical particles.
2. High ball forming rate and microbial survival rate: The new process can achieve a ball forming rate of over 90-95%, and the low-temperature and high air drying technology can achieve a microbial survival rate of over 90%.
3. The process flow is short and the operating cost is low. The organic raw materials used in this process do not require pre-treatment such as drying and crushing. The process flow is short and the operating cost is low (if traditional granulation processes such as disc or drum are used, the organic raw materials with a moisture content of about 30% after fermentation need to be baked to below 13% and crushed to 80 mesh or above, and the amount of organic materials added cannot exceed 30%).
