At present, the main granulation methods of organic fertilizer in the market are extrusion granulation and agglomeration granulation.
The common equipment of extrusion granulation is double roller granulator, which is a widely used pelletizer among organic fertilizer granulators. It is an extrusion sliding model and can continuously produce one-time roll forming. In addition, extrusion granulation equipment includes flat die pellet mill and ring die pelleting machine
The common equipments for agglomeration granulation are disc granulator and rotary drum granulator.
Disc granulator is a kind of mature equipment for organic fertilizer granulation. The angle of the disc is an integral arc structure. The material entering the disc is sprayed with an appropriate amount of liquid by the atomizing nozzle. After the granulator rotates, it is made into a finished product. After a certain amount is formed, it is thrown out with the rotation inertia of the disc.
Rotary drum granulator is driven by the main motor to drive the belts and pulleys, which are transmitted to the driving shaft through the reducer, and the split gears mounted on the driving shaft mesh with the large gear ring fixed on the body and work oppositely. The material is added from the feeding end, and it is made into particles by the special structure inside the cylinder, and finally flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.
The two in one npk fertilizer granulator uses the high-speed rotary mechanical stirring force and the resulting aerodynamic force to make the fine powder continuously realize the process of mixing, granulation, spheroidization and densification in the granulator, so as to achieve the purpose of granulation. The granulator is a new type of organic fertilizer granulator developed by our company. Wet fertilizer granulator is widely used in the granulation of organic fertilizer and npk compound fertilizer. Due to the high granulation rate, stable operation, strong and durable equipment, long service life, coupled with the stable base design, its operation is more stable, and is selected as the ideal product by the majority of users.
