Commonly used granulating organic fertilizer equipment are: disc granulator machine, drum granulator, wet granulator, roller extrusion granulator, flat die granulator, ring film granulator. The selection of the granulator should be determined according to the local fertilizer sales market. The shape of the granules is different, the process of the organic fertilizer equipment is also different, and the fertilizer granulator machine price is also different. Next, let’s talk about the drum granulator.
The principle of drum granulation is that the material relies on the surface tension, the right amount of liquid phase, the extrusion force generated by the rolling between the materials, and the material takes small particles as the core in the correct direction of movement in the granulator, and sucks in the rolling process. Small attached, glued into a ball. The higher the rolling frequency within a certain period of time, the higher the spheroidization rate, and the more rounded the pellets are after forming.
The rotary drum granulator adopts a variety of combined lifting devices. Set up a retaining ring at the feed end and the middle part of the simplified, and the tail is light. The middle retaining ring of the organic fertilizer drum granulator divides the simplified into two districts, the front district is the mixing granulation area, and the rear district is the particle polishing area. At the same time, High efficiency, reducing coal consumption by about 20%. The reasonable equipment structure of the organic fertilizer equipment conversion granulator reduces the floor space, the production capacity is large, and the operation is simple. Its technology is mature, high temperature industry, safe and reliable, energy saving and environmental protection, which greatly saves costs.
In addition, 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 of the material. In view of this situation, we can solve it by adjusting the speed of the granulator and installing a small copy board inside.
