Production Process of Organic Fertilizer Disc Granulator for Chicken Manure Treatment
When the organic fertilizer production process is processed by disc granulator, the organic matter should be crushed first to provide favorable conditions for the granulation of disc granulator. Chicken manure from farms is suitable for the production of organic fertilizer, and the production efficiency of organic fertilizer from chicken manure is good. The organic fertilizer disc production process can make full use of chicken manure waste and convert the organic matter in chicken manure into organic fertilizer. Organic fertilizer has acid-alkali buffering effect, which can prevent soil acid-alkali damage and salt damage, and is conducive to the prevention and control of soil degradation and desertification. Moreover, the organic fertilizer made by disc granulator has comprehensive nutrients, which is conducive to water and fertilizer conservation, improving biological flora and creating a good ecological environment for the growth of beneficial microorganisms.
Under the condition that the organic material accounts for 30% to 40%, NPK inorganic fertilizer is added in a ratio of 10:4:4, and granulation is carried out by using urea, superphosphate and potassium chloride. When disc granulator is used to treat organic fertilizer, the granulation size of raw material has a great influence on granulation. When organic matter is not crushed, the pelleting rate is low. If the organic matter is crushed and screened before entering the disc pelletizer, the pelletizing rate of the disc pelletizer can be significantly increased. Therefore, in actual production, in the organic fertilizer production process with disc granulator as the core, when chicken manure is used as organic matter, it is better to choose chicken manure containing a small amount of sawdust. Peat is added to the raw material for granulation. In the second crushing and return of organic fertilizer production process, large particles are pulverized together with fine powder, which not only saves labor and energy, but also improves production efficiency.
