Operation process of organic fertilizer production equipment: organic fertilizer raw materials (livestock manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.) are fermented and then enter the semi-wet material crusher for crushing, and then add elements such as nitrogen, phosphorus and potassium (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make the mineral elements meet the required standards, and then have a mixer to stir, and then enter the granulation mechanism particles, and then dry after coming out, The qualified products are screened by the screening machine and packed. The unqualified products are returned to the granulator for granulation.
Among them, the reasonable collocation of the fineness of raw materials is crucial for the production process of organic fertilizer. The fineness of the whole raw material should be matched as follows: 100-60 mesh raw material accounts for about 30-40%, 60-mesh raw material accounts for about 35%, and small particles with 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 particles after granulation. However, in the production process, the use of super proportion
