There are many types of fertilizer granulators on the market today. They all have their own advantages, so how do you know which granulator is right for you?
1. Consider raw materials for choosing fertilizer granulator machine:
Different granulation methods are required depending on the characteristics of the different raw materials. If rolling granulation is considered, it is necessary to check whether the powder has sufficient fineness. If the raw material particles are too large, it is not suitable to use rolling granulation (rolling granulation mainly has a disc granulator and a Conversion granulator); For granulation, it is necessary to consider whether the original powder has certain plasticity after kneading with water or other liquids (the extrusion granulation here mainly refers to the Roller extrusion granulator); if it is a wet pulverized suspension, it is required Consider whether it is easy to atomize. If it is easy to atomize, spray granulation may be considered. However, spray granulation is required to consider the heat sensitivity of the raw material.
2. Consider product requirements for choosing fertilizer granulator machine:
The particle size of the products obtained according to different granulation methods varies greatly, such as the particle size of spray granulation is small, but the rehydration performance is good. The size of the extruded granulated product is generally large, and even pellets can be prepared. The product obtained by the method of stirring mixing granulation, fluidized granulation, etc. is a spherical granule with irregular shape, and can be granulated by a Organic fertilizer throwing machine at a the next step.
3. Consider other factors for choosing fertilizer granulator machine:
The processing capacity of different granulation methods varies greatly, and the space occupied by equipment is also very different. Therefore, investment in equipment and civil engineering and processing costs must be considered. Dry granulation inevitably leads to dust generation. However, wet granulation requires drying after granulation and energy consumption, all of which are considered in the design of the granulator process.
