Chicken manure organic fertilizer production process

The production process of chicken manure organic fertilizer: organic fertilizer raw materials (animal manure, domestic garbage, dead branches, biogas residue, waste bacteria, etc.) are fermented and then enter the semi-wet material crusher for grinding, and then add elements such as NPK. (Pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to achieve the required standard of mineral elements, then stir with a mixer, enter the granulation mechanism particles, been dried,  and at last pass through the screen machine.

After that the qualified products will be packaged, but the unqualified return to the granulator again. Among them, the reasonable combination of the fineness of the raw materials is crucial for the organic fertilizer production. The higher fineness of the raw material, the better the viscosity and surface of the granulated particles.

However, in the production process, the use of over-proportioned high-fineness materials is prone to be problems such as excessive particles and irregular particles due to excessive adhesion.
