How to Choose Suitable Organic Fertilizer Granulators for Processing Fertilizer in Duck Farms

  According to the survey, the utilization rate of chemical fertilizers in my country is only 35% to 40%, and the rest is fixed by soil or leached by rainwater, causing environmental problems such as water pollution and eutrophication of lakes. Experts urgently call for reducing the use of chemical fertilizers, using more new biological fertilizers, and applying more organic fertilizers. The vast number of farmers also urgently need a new type of fertilizer to meet the needs of agricultural production.

The organic fertilizer npk fertilizer production line is mainly that the previously fermented organic fertilizer raw materials are crushed and then screened, and then the raw materials of the binder and other components to be compatible are measured, batched and mixed in an automatic batching mixing system according to the proportioning requirements ( Or after further drying to produce powdered organic fertilizer), the fully mixed material is uniformly and continuously fed into the granulator by the belt conveyor for granulation.

Choose a suitable organic fertilizer granulator according to specific process requirements. There are many types of granulators, such as roller extrusion granulator, disc granulator, rotary drum granulator, etc. For those with strict particle size control, it is recommended to use a roller extrusion granulator, and for those with general requirements for particle size and larger output, it is recommended to use a drum granulator for organic fertilizers.
Basically all granulation drying processes can be granulated with a double roller granulator. In particular, the particle size of the raw material powder is less than 2 mm, preferably less than 1 mm, which is very suitable for extrusion granulation. Crushed stone, powder, crystalline, granular and pellet raw materials are suitable. For potassium chloride, lower cost standard grades and by-products or products too fine to mix are suitable for extrusion. Although granular urea can be used, powdered or crystalline urea of ​​very small size is more suitable. In some cases, the particle size of the raw material varies so much that larger particles should be broken up first, resulting in a more even distribution of nutrients in the product.

  There is a huge demand for bio organic fertilizers in China, especially for some economically efficient and high-quality bio organic fertilizers, which are more popular among farmers. Therefore, opening an organic fertilizer equipment processing fertilizer factory can yield substantial returns. Organic fertilizer trading market. The production of green fruits and vegetables cannot be separated from organic fertilizers. A large amount of organic fertilizer is piled up and wasted in urban areas, and there is a huge demand gap for organic fertilizer in rural areas. If a rural organic fertilizer trading market is established, a bridge between supply and demand can be established, and the production of organic fertilizer through processing of bio   organic fertilizer equipment   can turn waste into treasure. How much does the entire set of equipment for processing bio organic fertilizers cost? 1. Determine the size of  organic fertilizer equipment , such as the annual p...

  Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of  organic fertilizer production equipment  and the relevant situation of organic fertilizer fermentation equipment. Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful. 1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer ...
