Factors affecting the granulation speed of organic fertilizer rotary drum granulator

 The principle of rotary drum granulator is that the material relies on the surface tension, the right amount of liquid phase, the extrusion force generated by the rolling between the materials, and the material takes small particles as the core in the correct direction of movement in the granulator, and sucks big during the rolling. Small attached, glued into a ball. The higher the rolling frequency in a certain period of time, the higher the spheroidization rate, and the more rounded the pellets are after they are formed.


1. In the npk production line, we have encountered two situations due to the different friction between the material and the wall of the granulator. The inner surface of the granulator has a large surface finish, which reduces the friction between the material and the cylinder wall, and weakens the upward movement of the material. If the material does not roll, particles cannot be produced. In response to this situation, we can solve it by adjusting the speed of the granulator and installing a small copy board inside.
2. The material in the rotary drum granulator is seriously sticking to the wall, and the friction between the material in the granulator and the cylinder wall is enhanced, and the material in the granulator is lifted too high, causing the material to be thrown down from the top, so that the formed particles are not round. And too many large particles, we think there are two reasons for this situation: on the one hand, it is caused by too many viscous materials. The inside of the machine is not smooth, which is solved by changing the internal material and increasing the smoothness of the granulator.

  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 ...
