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 and high fineness materials is easy to cause problems such as oversized particles and irregular particles due to poor viscosity.

If pig manure can be processed into organic fertilizer, it can not only effectively use pig manure resources, but also not worry about market. Fermented pig manure can be used directly as fertilizer or as raw material to produce compound organic fertilizer, which can thoroughly solve the environmental pollution problem caused by livestock manure and carcasses, and ensure the large-scale, green and sustainable development of the aquaculture industry.

Organic fertilizer processing equipment has many advantages in processing and producing organic fertilizer. Through services close to farmers, land and consumer groups, we can find scientific and reasonable formula, production characteristics, and high value-added organic fertilizer products, so that the whole industry can enter the track of sound development. The pace and combination of grass-roots agricultural production to help farmers increase production and create income.
