How to make granular organic fertilizer?

Generally speaking, the production of granular organic fertilizer is mainly divided into two parts. One is fermentation and the other is granulation. The equipment used mainly includes fermentation compost turner equipment, crushing equipment, mixing equipment, granulating equipment, drying and cooling machine and so on. Following are the process:
The recovered raw materials like animal dung is directly fed into the fermentation zone. After primary fermentation and secondary aging, the odor of raw materials can be eliminated. Fermentation bacteria can be added at this stage to decompose the crude fiber in it to meet the requirements of the size of crushed particle. The fermented material that has completed the secondary aging and stacking process is crushed and enters the mixing system. Before mixing, N, P, K and some other trace elements are added to the mixing system in a certain proportion. The mixed materials are transported into the granulation system, the granules enter the cooling system after the dryer. When the temperature of materials are brought to room temperature, they can be screened. The granules that meet the requirements enter the coating machine to wrap the film and then they can be packaged. The granules that do not meet the requirements are crushed by the crusher and then returned to the granulation system to continue granulation. The finished product is automatically packaged.
