The organic fertilizer rotary drum granulator is suitable for small and medium-sized fertilizer plants

2022/06/30

The principle of drum granulation is that materials rely on surface tension, an appropriate amount of liquid phase, extrusion force generated by rolling between materials, and small particles are taken as the core in the correct movement direction of materials in the granulator to absorb large particles and adhere to small particles and form balls during rolling. The higher the rolling frequency in a certain time, the higher the balling rate and the rounder the particles are after forming.

The organic fertilizer rotary drum granulator used in small and medium-sized fertilizer plants is a rotating circular granulator with a diameter of 1.2 - 2.4m and a length of 3 - 6m. A material retaining ring is arranged at the feeding end and the middle part of the simplified body, and the tail is smooth. The middle retaining ring of the organic fertilizer drum granulator divides the simplified body into two areas, the front area is the mixing granulation area, and the rear area is the particle polishing area.

The organic fertilizer rotary drum granulator process does not have the phenomenon of limited size and sticking of four plates, which is conducive to the classification of dry and wet particles. The relative granulation ratio is low, generally 40% - 60%. Therefore, the reverse material rate is high, but the requirements for material mixing and degree in the mixing process are relatively low.

In the production process, we have encountered two situations due to the different friction between the material and the cylinder wall of the granulator. The internal surface finish of the granulator is large, which reduces the friction between the material and the cylinder wall and weakens the upward movement force of the material. If the material does not roll, it will not produce particles. In view of this situation, we can solve it by adjusting the rotating speed of the granulator and installing a small board inside.
