Production process of pig manure organic fertilizer production line

Organic fertilizer production line can be classified into powder organic fertilizer production line and granular organic fertilizer production line. Granular organic fertilizer production line generally includes most of the equipment of powder organic fertilizer production line. In other words, in order to produce granular organic fertilizer, we must first ferment and then produce it into powder organic fertilizer. In addition, the organic fertilizer production line also has the advanced degree of equipment. The advanced organic fertilizer production line has the advantages of labor saving, energy saving, small land occupation, low fertilizer cost and no environmental pollution.

The process of pig manure organic fertilizer production line is as follows:

1. Raw material ingredients: chicken manure, pig manure, cow dung, biogas residue and other animal wastes or raw materials that can be fermented or have fertilizer effect after treatment shall be provided in a certain proportion (according to market demand and soil test results in different regions).

2. Raw material mixing: mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency content of fertilizer particles.

3. Raw material granulation: the evenly stirred raw materials are sent to the fertilizer granulator machine for granulation (rotary drum fertilizer granulator machine or extrusion fertilizer granulator machine can be used).

4. Particle drying: the fertilizer granulator machine made particles into the dryer, drying the moisture contained in the particles, increasing the strength of the particles, easy to save.

5. Grain cooling: the temperature of the dried fertilizer particles is too high and easy to agglomerate. After cooling, it is easy to pack, store and transport.

6. Particle classification: the cooled particles are graded. The unqualified particles are crushed and re granulated, and the qualified products are screened out.

7. Finished product coating: fertilizer production machine to coating the qualified products to increase the brightness and roundness of the particles.

8. Packaging of finished products: bag the coated particles, that is, finished products, and keep them in a ventilated place.
