When choosing an compound organic fertilizer granulator, many customers are often confused because they are faced with many fertilizer equipment classifications and do not know how to choose the right equipment. The following will introduce the information about the organic fertilizer granulator in detail for your reference.
We often receive inquiries from many customers asking about the use, function, granule effect and other issues of the organic fertilizer granulator. Many customers find it difficult to determine what kind of equipment they need. According to the use requirements of the material, it is key to choose the appropriate granulation method.
The granulation methods of organic fertilizers are mainly divided into two categories: dry granulation and wet granulation.
Dry granulation
Fertilizer dry granulator is a process for granulating raw materials with low moisture content. Generally, the moisture content of raw materials below 10% is considered a critical value. In the dry granulation process, the resulting particles are mostly oblate particles, similar to common granular potash fertilizers. With the upgrading of domestic industries and the continuous improvement of environmental protection standards, many chemical and construction material powders need to be made into granular form to meet demand.
Features of double roller extrusion granulator
Double roller extrusion granulator is a common fertilizer granulation equipment for dry granulation.
1. Through one-time extrusion granulation, oblate fertilizer granules can be formed, and no additives are required in the granulation process.
2. Granulation can be carried out at room temperature, and no drying equipment is required after granulation, which reduces energy consumption.
3. The size and hardness of the granules can be changed by adjusting the pressure between the rollers and the size of the mold.
4. It occupies a small area, has low energy consumption, and the granulator material has good anti-corrosion properties.
5. High production efficiency and continuous production.
In general, the dry extrusion granulator has the advantages of simple operation, high production efficiency, and stable granule quality. It is suitable for the granulation needs of various raw materials and is one of the commonly used granulation equipment in many industries.
Wet granulation
Wet granulation is a granulation method for producing fertilizer granules. Its main feature is to process materials with a moisture content of more than 20%. In the wet granulation process, a variety of equipment and methods are used, such as disc granulation, drum granulation, and stirring tooth granulation. Although these traditional granulation methods have a long history, they have made great progress in continuous improvement with the increase in the use environment and processing requirements of different materials. Especially in recent years, organic fertilizer granulation has been more popular. The particle size of these granules is generally between 1mm and 6mm, and they are usually prepared by the above-mentioned methods. Therefore, as an important part of fertilizer production, wet granulation has huge development space. It has a wide range of applications in the preparation of different types of fertilizers, and is constantly being improved and improved with the advancement of technology.
Features of rotary drum granulator
As a wet granulation equipment, the rotary drum granulator is widely used in the granulation production of organic fertilizer.
1. High efficiency: 10 tons of finished fertilizer granules can be produced per hour with low return rate.
2. Wet granulation: the surface of fertilizer granules is smoother, the shape is regular and the hardness is high.
3. Anti-corrosion performance: special rubber inner wall, anti-corrosion and anti-sticking, with heat preservation function, improves drying efficiency.
4. Wide application: The drum granulator is suitable for granulation of various raw materials, including organic fertilizer, chemical fertilizer, compound fertilizer granules, etc.
5. Energy saving and environmental protection: It can effectively treat organic waste, recover heat at the same time, and save energy.
