Double roll extrusion granulator: Double roll extrusion granulator belongs to dry granulation, without drying process, with high granulation density, good fertilizer efficiency, and full organic matter content. It saves the cost of purchasing a dryer and cooling machine, and there is no need to burn coal in the later stage, which saves a significant amount of funds. However, the shape of the granules produced by the squeezing granulator is flat and circular, which makes it easy for the machine to get stuck during sowing in the field crop machine, and the fluidity is not very good. So if organic fertilizer is produced for machine sown farmers, it is recommended to use this granulation process with caution and choose compound fertilizer and mixed fertilizer.

Drum granulator: The drum granulator is a process that has been used for granulating compound fertilizers, and can also be used for producing organic fertilizers. However, the granulation rate is relatively low. If producing organic and inorganic organic fertilizers, this process can be chosen.

Disc granulator: Disc granulator is a relatively traditional granulation process. I personally highly recommend this type of granulator, which has smooth granulation, good appearance, and low equipment price. The only drawback is its low density;. At present, people are pursuing new and innovative methods of granulation, so the number of users is gradually decreasing.

Stirring toothed organic fertilizer granulator: Stirring toothed organic fertilizer granulator, this type of granulator is currently the hottest selling product in the market and is also widely favored by customers. This process has high yield and smooth processing. If an organic fertilizer rounding machine is added, the granulation can be comparable to disc granulation. But we need to purchase a dryer and a cooling machine. So the entire set of equipment for this process is relatively expensive.

Ring mold granulator: The ring mold granulator has the highest particle density, and the particles will not scatter during sales and transportation. However, in the later stage, a rounding machine must be added to achieve the finished product of round particles. This granulation process is relatively expensive.
