There are three types of granulators used in general organic fertilizer production lines:

1. Organic fertilizer drum granulator

The drum granulator is a molding machine that can make materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer equipment industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working mode is wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotating motion of the cylinder, the material particles are squeezed and agglomerated into balls.

2. Roller extrusion granulator

The roller extrusion granulator is an improved product that absorbs new technologies of foreign granulators. The machine is equipped with a feeding system that combines a pre-continuous feeder with a mechanical vibration device and a forced feeding spiral feeder hopper to ensure the continuity, sufficiency and uniformity of the feeding, which is a crucial step. Uniformly distributed arc grooves are engraved on the paired rollers, which is conducive to the material biting into the rollers, forming an arc groove sealing cavity (belt) during operation, which is also conducive to the compaction of the material, reducing the forming pressure of the unit and the load of the main machine, and improving the sheet rolling productivity.

3. Organic Fertilizer Disc Granulator

The disc bottom of the organic fertilizer disc granulator is reinforced with multiple radiation steel plates, which is sturdy and durable and will never deform. The thickened, heavier and sturdy base design of the organic fertilizer disc granulator does not require anchor bolts to fix it, and it runs smoothly.
