The granulation process is the core part of the fertilizer production line. The granulator is used to manufacture dust-free fertilizer granules with controllable size and shape.
The granulator achieves high-quality uniform granulation through continuous mixing, collision, inlay, spheroidization, granulation, and compaction processes.
The types of granulators are:
Roller extrusion granulator, organic fertilizer granulator, drum granulator, disc granulator, compound fertilizer granulator, buffer granulator, flat die extrusion granulator, double screw extrusion Customers can choose different granulators such as granulators according to the actual composting raw materials, sites and products.
The different points of various granulators:
l The extrusion granulator is a dry granulation, no drying process, high granulation density, good fertilizer efficiency, and full organic matter content; it also saves the money for buying dryers and coolers, and does not need to burn coal in the later stage. This saves a large part of the funds. However, the pellets produced by the extrusion granulator are oblate. It is easy to jam when the field crops are machined. The fluidity is not very good. It is recommended to use compound fertilizer and compound fertilizer. Therefore, if it is organic for machine-seeded farmers Use this granulation process with caution for fertilizers.
l The drum granulator is a process that has been used for compound fertilizer granulation. It can also be used to produce organic fertilizers, but the granulation rate is low. If you produce organic, inorganic, and organic fertilizers, you can choose this process.
l The disc granulator is a more traditional process. I personally recommend this granulator. The granules are smooth and the appearance is good. The only disadvantage is the low density.
l Organic fertilizer granulator. This granulation process is the most popular product sold in our factory, and it is also a product that is widely favored by customers. This process has high yield and smooth processing. If you add an organic fertilizer rounding machine, the pellets can be produced. Comparable to disc granulation. However, it is necessary to purchase dryers and coolers. The price of the complete set of organic fertilizer equipment for this process is relatively expensive.
l The flat die granulator has the highest granule density, and the granules will not be scattered during the sales and transportation, but a rounding machine must be added in the later stage to realize the finished product of round granules.
l The compound fertilizer granulator is an excellent process product for organic and inorganic granulation. The internal special design is not easy to stick to the wall and has high yield; it can also be used to make compound fertilizers such as high-nitrogen fertilizers. Raw materials with higher viscosity can use this granulation process.
