The Organic fertilizer production line is a complete set of production equipment to produce natural Organic fertilizer through a series of processing and treatment of animal and plant residues such as fresh chicken manure, cow manure, pig manure, sheep manure, solid waste straw and other residues as raw materials. The Organic fertilizer production line needs two steps to process commercial Manure: early fermentation and processing part and deep processing and granulation part.
Process flow of Organic fertilizer production line: raw material batching → mixing → crushing and caking → granulation → primary screening → particle drying → particle cooling → secondary screening → coating of finished particles → quantitative packaging of finished products.
Each link of the process flow of Organic fertilizer production line:
1. Ingredients of raw materials: generally, 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 can be selected in a certain proportion (mainly determined according to local market demand and local soil test results);
2. Mixing and stirring: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency content of the fertilizer particles, and use a horizontal mixer or a disc mixer for mixing and stirring;
3. Agglomeration and crushing: Crush the mixed and evenly stirred raw materials into large blocks for subsequent granulation processing, mainly using chain crushers, etc;
4. Material granulation: The evenly stirred and crushed materials are fed into the granulation machine through a belt conveyor for granulation (which can be done using a rotary drum granulation machine, a pair of roller extrusion granulation machine, a disc granulation machine, etc.). This step is an essential and most important part of the organic fertilizer production process;
5. Primary screening: Preliminary screening of semi-finished particles, returning unqualified particles to the mixing and mixing process for further processing, usually using a drum screening machine;
6. Particle drying: The particles made by the granulator and screened by the first stage are fed into the dryer to dry the moisture contained in the particles, increase their strength, and facilitate storage. Generally, a rotary drum dryer is used;
7. 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, and are cooled using a cooling machine;
8. Particle secondary classification: Classify the cooled particles, crush the unqualified particles into new particles, and screen out the qualified products. A secondary drum screening machine can be used for screening;
9. Finished product particle coating: Coating qualified products to increase the brightness and roundness of the particles, making the appearance more beautiful. Generally, using a coating machine for coating;
10. Quantitative packaging of finished particles: The coated particles, also known as finished particles, are temporarily stored in the silo through a belt conveyor, and then connected to electronic quantitative packaging scales, sewing machines, and other automatic quantitative packaging and sealing bags. They are stored in a ventilated place to achieve full automation.
