Process flow of processing equipment for granular organic fertilizer from livestock and poultry manu

Update time : 2022-10-09 Publisher:Tongda

The general production process flow of organic fertilizer is as follows: the raw materials of organic fertilizer (animal dung, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.) are fermented and then crushed in a semi wet material grinder, and then added with elements such as nitrogen, phosphorus, potassium chloride, ammonium chloride, etc. (pure nitrogen, phosphorus pentoxide, potassium chloride, etc, The qualified products shall be packed through screening machine, and the unqualified products shall be returned to the granulator for granulation. Among them, the reasonable matching of raw material fineness is crucial to the production process of organic fertilizer. The higher the fineness of raw materials, the better the viscosity, and the higher the surface finish of granulation particles. However, in the production process, the use of super proportion of high fineness materials is prone to problems such as too large particles and irregular particles due to too good viscosity.


Organic fertilizer is mainly made of livestock manure, domestic garbage and plant straw. The production process of this organic fertilizer is roughly as follows: raw material drying → crushing → fermentation → blending (mixed with chemical fertilizer and other organic inorganic substances to make the content of nitrogen+phosphorus+potassium ≥ 4% and organic matter ≥ 30%).

Process Flow of Straw Organic Fertilizer Production Line Equipment Processing Organic Fertilizer:

Crop straw: Crop straw is one of the important fertilizer varieties. Crop straw contains N, P, K, Ca, s and other nutrients necessary for crops. Cake fertilizer: rapeseed cake, cottonseed cake, bean cake, sesame cake, castor cake, tea seed cake, etc. Clay fertilizer: unpolluted river mud, pond mud, ditch mud, harbor mud, lake mud, etc. For example, if the raw material is humic acid or peat, there is no fermentation in this organic fertilizer production process, so fermentation is unnecessary. The rest steps are the same as above. The production process of organic fertilizer is closely related to the equipment configuration of the organic fertilizer production line. Generally, the complete equipment of the organic fertilizer production line is mainly composed of fermentation system, drying system, deodorization and dust removal system, grinding system, batching system, mixing system, granulation system, screening system and finished product packaging system.
