Equipment composition and process flow of cow manure organic fertilizer production line


The raw materials for producing organic fertilizers are quite extensive, and the most common ones are animal manure such as chicken manure, pig manure, and cow manure. This type of raw material needs to undergo biological fermentation and then meet the standards for harmless treatment, in order to further produce commercial organic fertilizer. The process flow of the complete set of equipment for organic fertilizer production line is as follows: after the fermentation of organic fertilizer raw materials (animal manure, household waste, dead branches and leaves, biogas residue, waste bacterial strains, etc.), they enter the semi wet material crusher for crushing, and then add elements such as nitrogen, phosphorus and potassium (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to meet the required standards of mineral elements. Then, a mixer is used for stirring, and the particles enter the granulation mechanism. After coming out, they are dried, Through the screening machine, qualified products are packaged, and unqualified products are returned to the granulator for granulation.

Equipment composition and process flow of organic fertilizer production line:

1. The ratio of raw materials per ton is 500 kilograms of pig manure (or other animal manure), 300 kilograms of auxiliary materials, 200 kilograms of bacterial residue, and 100 grams of RW bacterial agent;

2. Stacking, according to the above raw material ratio, according to the needs, the stacking length is unlimited, with a width of 4 meters and a height of 2 meters. When stacking materials, it is necessary to stack them layer by layer evenly;

3. Add the bacterial agent, expand the volume of the bacterial residue in a 1:5 ratio, mix evenly, and sprinkle it on the surface of the pile according to the number of piles;

4. Stir and ferment, use a blender to stir the pile evenly. After the temperature rises to 60 degrees Celsius or above, flip the pile every 4-5 days. After 15 days of fermentation at 60 degrees Celsius or above, fold the pile up;

5. Screening processing, fermentation is carried out according to the above steps, and after screening and deep processing, it becomes pure organic fertilizer;

6. Granulation refers to the granulation of fermented pure organic fertilizer. Choose granulators based on different raw materials, such as disc granulators, extrusion granulators, and integrated extrusion ball throwing machines;

7. Drying, cooling, and packaging: Newly made particles have a relatively high moisture content and need to be dried to below 20% of the organic fertilizer standard. The dried particles of organic fertilizer are cooled by a cooling machine before being directly packaged.
