Advantages and disadvantages of organic fertilizer granulators in wet granulation production lines

 Granular fertilizer can add some inorganic components in fertilizer to improve fertilizer efficiency, while powdery fertilizer is easy to absorb moisture and caking if inorganic components are added. Granular fertilizer is more convenient to apply, especially in some large-scale planting bases, mechanical fertilization is generally used. If mechanical fertilization is used, only granular fertilizer can be used. If it is powdery, it is easy to fly everywhere.


Wet granulation is divided into many kinds of equipment, the early disc granulator, drum granulator, stirring granulator, organic fertilizer combination granulator and so on. Each granulation method is different for different raw materials, but it has one characteristic, that is, the moisture content of raw materials is generally 25% - 60%, and the requirements of moisture content are different with different equipment.
Disc granulator is an early granulation equipment for wet granulation. The moisture requirement is generally about 50%. The disc is used to make the materials roll on the disc and slowly stick together to form granules. It is suitable for relatively fine raw materials with low adhesion. Disadvantages: too high moisture, too much consumption in the later stage, and too high material requirements.
Among these granulating equipment, the most outstanding technology and performance are stirring teeth organic fertilizer granulator machine and organic fertilizer combination granulator machine. If it is pure organic matter granulation, it is recommended to choose stirring teeth granulation, which is suitable for a wide range of applications, and the water content can be controlled between 25% - 45%. Organic fertilizer combination granulator is mainly used to add some inorganic components (nitrogen, phosphorus, potassium, etc.) into the organic matter. The wet granulation material requires high moisture, and the consumption of drying and cooling is increased.

  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...

Main production process guidance of organic fertilizer production equipment

Image
  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 ...
