Technological process of chicken manure organic fertilizer production line


The production of organic fertilizer includes: raw material selection (chicken manure, etc.) → drying and sterilization → mixing of ingredients → granulation → cooling and screening → metering and sealing → storage of finished products.
Technological process of chicken manure organic fertilizer production line
The more complicated production process of chicken manure organic fertilizer 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 stirred by mixer After mixing, the granules are put into the granulating machine, 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 reasonable matching of the fineness of raw materials is very important for the process of fertilizer production line. According to the experience of organic fertilizer equipment and organic fertilizer production process, the fineness of the whole raw material should be matched as follows: raw material with 100-60 mesh accounts for about 30% - 40%, raw material with 60 mesh to 1.00 mm diameter accounts for about 35%, and small particles with 1.00-2.00 mm diameter account for about 25% - 30%. The higher the fineness of the material is, the better the viscosity is, and the higher the surface finish of the granulated particles is. 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.
