There are many types of organic fertilizer granulation machines on the market today, and they all have their own advantages. So, how do you know which granulator is more suitable for you?
1. Choose the raw materials of organic fertilizer granulation machine
According to the characteristics of different raw materials, different granulation methods are required. If rolling granulation is considered, it is necessary to check whether the powder has sufficient fineness. If the raw material particles are too large, rolling granulation is not suitable; when granulating, it is necessary to consider whether the raw powder has a certain degree of plasticity after kneading with water or other liquids. If it is a wet powder suspension, you need to consider whether it is easy to atomize. If atomization is easy, consider spray granulation. However, spray granulation needs to consider the heat sensitivity of the raw materials.
2. Consider product requirements when choosing an organic fertilizer granulation machine:
The particle size of the product obtained by different granulation methods varies greatly. For example, the particle size of spray granulation is small, but the rehydration performance is good. The particle size of extruded granulated products is generally larger, and uniform granules can be prepared.
3. Other factors should be considered when choosing an organic fertilizer granulation machine:
The processing capacity of different granulation methods is quite different, and the space occupied by the equipment is also very different. Therefore, equipment investment and civil engineering and processing costs need to be considered. Dry granulation will inevitably produce dust. However, wet granulation requires drying after granulation and consumes energy, which are all issues to be considered in the design of the granulation process.
