The design of the fertilizer granulation process
of chicken manure organic fertilizer pellet fermentation includes:
1. High-efficiency compound strain and its propagation technology;
2. Advanced raw material blending technology and biological fermentation system;
3. The best special fertilizer formula technology (the product formula of the best combination can be flexibly designed according to the local soil and crop characteristics);
4. Reasonable secondary pollution (exhaust gas and odor) control technology;
5. Design and manufacturing technology of organic fertilizer production line equipment.
The more complex chicken manure organic fertilizer production process is: organic fertilizer raw materials (animal manure, domestic garbage, dead branches, rotten leaves, biogas residue, waste bacteria, etc.) are fermented into a semi-wet material pulverizer for pulverization, and then nitrogen and phosphorus are added Potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements reach the required standard, and then a mixer is used for stirring, and then enters the fertilizer pellet machine
for granules, and then they are dried and passed The sieving machine screens, the qualified products are packaged, and the unqualified products are returned to the granulator for granulation.
Among them, the reasonable collocation of the fineness of the raw materials is very important for the organic fertilizer production process.
The fineness of the whole raw materials should be matched as follows: 100-60 mesh raw materials account for about 30%-40%, 60 mesh to 1.00 mm diameter raw materials account for about 35%, and small particles with a diameter of 1.00—2.00 mm account for about 25%-30%. , The higher the fineness of the material, the better the viscosity and the higher the surface finish of the granulated particles.
However, in the production process, the use of over-proportioned high-fineness materials is prone to problems such as excessively large particles and irregular particles due to excessive viscosity.
The production process of chicken manure organic fertilizer is closely related to the equipment configuration of the organic fertilizer production line. Generally, the complete set of equipment for the organic fertilizer production line is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulator machine for fertilizer, screening system And the finished product packaging system.
