With an annual output of 20,000 tons, the scale is large, so you can consider creating a granular organic fertilizer production line. The granular organic fertilizer production line includes two important processes, fermentation and granulation.
1. Fermentation process:
Mix chicken manure, straw, mushroom residue and other materials together, add fermentation agents, and under the action of fermentation agents, the pile will generally heat up in about 2 days. At this time, you can use a turning device to turn the pile to increase the oxygen content and moisture content of the pile. If the local environmental protection is strict, you can use a vertical fermentation tank for fermentation. The fermentation process of the vertical fermentation tank is fully sealed and contains a deodorization device, which will not cause environmental pollution.

2. Granulation process:
After the material is fully fermented and matured, it enters the granulation process. The finer the material, the better the shape of the particles, so it should be crushed first with a vertical crusher, and then screened with a drum screening machine. The unqualified materials enter the crushing link again, and the qualified materials enter the granulator. For the production of round granules using a granular organic fertilizer production line with an annual output of 20,000 tons, it is recommended to use a disc granulator, a stirring tooth granulator, etc., and for the production of cylindrical granules, it is recommended to use a flat die granulator and a roller extrusion granulator. After the granulation is completed, the screening machine is used for screening again. The unqualified granular materials enter the crushing-granulation process again, and the qualified granules enter the packaging machine.
In the granular organic fertilizer production line, the production process of fermentation and granulation is relatively simple, but the equipment selection is very important. Equipment with stable performance and excellent design can not only avoid production accidents, but also make the quality of organic fertilizer higher.
