Organic fertilizer equipment has played an important role in the green and environmentally friendly development of agriculture, achieving harmless and resourceful treatment of organic waste. Organic fertilizer production equipment processes organic waste into spherical particles of organic fertilizer, allowing for large-scale promotion of organic fertilizer. Many customers are not very familiar with the treatment technology of organic fertilizer equipment. Today, Taian Hongxin Environmental Protection will explain in detail:

The characteristics of coarse powder or irregular small block organic fertilizers after biological fermentation are high moisture content (30-40%), looseness (bulk density 0.3-0.4t/m ³), and high fiber content. The existing technologies for making spherical particle organic fertilizers from coarse powder or irregular small block organic fertilizers after biological fermentation mainly include the following:

1. Some manufacturers first dry the coarse powder or irregular small pieces of organic fertilizer to a moisture content of only 20-25%, and then use a flat die extrusion granulator or a roller extrusion granulator to extrude the dried organic fertilizer into cylindrical or flattened spherical particles. Although this method is more convenient to use, its flowability is still not very good, it is not suitable for machine sowing, and its appearance and appearance are poor;

2. Some manufacturers first use a flat die extrusion granulator to extrude coarse powder or irregular small pieces of organic fertilizer into short columnar particles (due to high moisture and fiber content, columnar particles also have certain plasticity), then polish and shape them into spherical particles, and then dry, cool, and screen the spherical particles to obtain qualified particles. This method does not require processing of raw materials, reduces the sequence of moisture, and greatly reduces production costs. However, this method also has some fatal weaknesses, which are that organic fertilizer is prone to arching, clogging, and bonding equipment, and has low output and high power consumption during the extrusion process;

3. Some manufacturers use traditional disc or drum granulation methods, which require drying coarse or irregular small pieces of organic fertilizer (moisture<15%), crushing them into very fine (greater than 100 mesh) powder, and then adding binders and inorganic fertilizers. The amount of binders and inorganic fertilizers added to the organic fertilizer cannot exceed 30%. Although this method can produce spherical particles, the processing cost is quite high due to the fact that the organic fertilizer is first fully dehydrated and crushed, then granulated with water and dried multiple times. Moreover, due to the low density of organic fertilizers, the particle strength is low, which is not conducive to storage, transportation, and machine sowing.

Therefore, in summary, the organic fertilizer industry urgently needs to introduce a high-yield, low-energy compression granulation equipment to overcome the disadvantages of traditional flat die extrusion granulators, such as easy arching, clogging, easy bonding equipment, low output, and high power consumption during the extrusion process. Organic fertilizer equipment perfectly solves the above problems. If you also have a procurement plan for organic fertilizer equipment, please feel free to visit our factory for more information
