Equipment introduction and process of cow dung organic fertilizer production line

Organic fertilizer projects have a short construction period, high return on investment, low market risk (generally at least 5 years of shelf life for organic fertilizer), short payback period (in case of busy farming, supply exceeds supply), and great market potential (China is vast and rich in resources, especially in Henan, Northeast, etc.) In a large agricultural province, the consumption is quite large), generally the investment can be recovered in one year and a profit is generated that year.

The organic fertilizer production line generally includes: raw material selection (chicken manure, etc.) → drying and sterilization → ingredient mixing → fertilizer pellet machine → cooling and screening → metering and sealing → finished product storage.



The more complicated chicken manure organic fertilizer production equipment process is: organic fertilizer raw materials (animal manure, domestic garbage, dead branches, rotten leaves, biogas residue, waste bacteria, etc.) are fermented into a semi-wet material crusher for crushing, and then added Nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements reach the required standard, and then a mixer is used for stirring, and then enters the organic fertilizer  granulator for granules, and then they are dried , Sieved by a sieving machine, qualified products are packaged, and unqualified products are returned to the granulator for granulation.

Among them, the reasonable mix of the fineness of the raw materials is very important for organic fertilizer production process. According to Zhengzhou Huaqiang Heavy Industry's years of experience in organic fertilizer equipment and organic fertilizer production technology, the fineness of the entire raw materials should be best matched as follows: 100-60 mesh raw materials account for about 30%-40%, and 60 mesh to 1.00 mm diameter raw materials account for about 35%, small particles with a diameter of 1.00-2.00 mm account for about 25%-30%. The higher the material fineness, the better the viscosity and the higher the surface finish of the granulated particles. However, in the production process, the use of a super-proportion of high-fineness materials is prone to problems such as excessively large particles and irregular particles due to excessive viscosity.
