The disc granulator has the characteristics of uniform granulation, high granulation rate, stable operation, durable equipment and long service life. It is an ideal equipment for granulation of organic fertilizer and compound fertilizer. Disc granulator plays an important role in organic fertilizer manufacturing process. The motor of this equipment is driven by flexible belt, which can start smoothly, reduce shock and improve the service life of the equipment. The bottom of the granulating tray is strengthened by several radiation steel plates, which are durable and never deformed. Disc fertilizer granulator has a thicker, heavier and stronger base design. It does not need anchor bolts to fix and runs smoothly.
The following points should be paid attention to when disc fertilizer granulator is in operation
1. Before starting, the temperature should rise for about forty or fifty minutes. The temperature can be raised to the point where the triangle belt of the motor can be pulled freely by hand, and the motor can be pulled eight to ten times continuously according to the normal working direction. Then continue to warm up for about 10 minutes, and then turn on, but continue to warm up, because normal production needs to continue to supplement heat.
2. When the granulator is working normally, the temperature of the granulator should be kept stable, and the temperature should not be too high or too low. In the vicinity of the vent, the temperature should be maintained at about 200 degrees Celsius until the nose position is reached.
3. When the disc granulator is running, the organic fertilizer should be fed evenly. The processing speed of the equipment should be matched with the feeding speed properly. Otherwise, it will affect the quality and yield of particles.
4. When the fertilizer manufacturing process stops working, the main engine should completely cut off the power supply. The nose with wrench must be removed. Preheat separately before next use.
Disc fertilizer granulator is not suitable for organic fertilizer with high crude fiber content. Because this kind of pan type granulator mainly forms centrifugal force by rotating, and then depends on the moisture of the material to adhere to each other to form spherical particles. There is no external force factor in the granulation process, and the inherent characteristics of crude fibre materials are light density, poor adhesion and difficult forming. Therefore, the pressure of forming balls is very high only by centrifugal rotary rolling.
