Attention should be paid to the following items when producing organic fertilizer from livestock manure: 1. Efficient compound bacteria and its propagation technology; 2. Advanced raw material blending technology and biological fermentation system; 3. The best special fertilizer formula technology (the best combination product formula can be designed flexibly according to the local soil and crop characteristics); 4. Reasonable secondary pollution (waste gas and worry gas) control technology; 5 Design and manufacturing technology of complete fertilizer process equipment.
The livestock manure organic fertilizer production line
with higher automatic yield is as follows: the raw materials of organic fertilizer (animal manure, domestic waste, dead branches and rotten leaves, biogas residue, waste bacteria, etc.) are fermented and then crushed by semi wet material crusher, and then nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are added to make the mineral elements reach the required standard, and then There is a mixer for mixing, and then enter the granulation machine. The particles are dried after coming out, and screened by the screening machine. The qualified products are packaged, and the unqualified ones are returned to the granulator for granulation.
Among them, the fineness of raw materials is very important for the organic fertilizer production line. The fineness of the whole raw material should be matched as follows: the raw material with 100-60 mesh accounts for about 30% - 40%, the raw material with 60 mesh to 1.00 mm diameter accounts for about 35%, and the small particles with 1.00-2.00 mm diameter 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. But in the production process, the use of super proportion of high fineness materials, easy to cause too large particles, irregular particles and other problems due to good viscosity.
