How to compress and granulate organic fertilizer in an organic fertilizer production line? With the development of environmental protection and organic agriculture, the use of organic waste to make organic fertilizers through biological fermentation has developed rapidly in my country, making organic waste treatment harmless and resource-based. However, most of the organic fertilizers obtained through biological fermentation are in the form of coarse powder or irregular small pieces, which are inconvenient to use, especially not conducive to large-scale machine sowing.

Making spherical granular organic fertilizers from coarse powder or irregular small pieces of organic fertilizers obtained through biological fermentation is the key to solving the problem of large-scale promotion and use of organic fertilizers; at the same time, in order to avoid uneven fertilizer effects when making granules, these raw materials will be crushed, stirred, and NPK will be added, which can not only increase the nutritional content of organic fertilizers, but also distribute these nutrients evenly and consistently to each granule.

Next, I will explain how to compress and granulate organic fertilizers in the organic fertilizer production line: The characteristics of coarse powder or irregular small pieces of organic fertilizers after biological fermentation are high moisture (30-40%), looseness (bulk density 0.3-0.4t/m3), and high fiber content. The existing organic fertilizers in coarse powder or irregular small pieces after biological fermentation are made into spherical particles.

Organic fertilizer granule production technology:

First, these organic fertilizers are decomposed into small molecules that can be directly absorbed and utilized by plants. During the fermentation period, the organic fertilizer turning machine is required to continuously turn the compost to avoid insufficient internal oxygen supply, and even produce anaerobic reactions that affect the composting rate;

After the composting is completed, the organic materials and the trace elements to be added are crushed and evenly distributed, and then transferred to the automatic batching system. After the material formula is set in advance, the materials are scientifically and accurately discharged;

A conveyor belt is provided under the batching system to transport the materials to the horizontal mixer at a uniform speed. After mixing evenly, it enters the next granulation link;

After granulation, it is dried and cooled, thereby linking packaging and transportation to achieve automatic continuous production. After the granulation stage is completed, new fertilizer manufacturers can carry out screening, coating and other processes according to their needs to further improve the economic value of the product.
