The disc granulator is a classic equipment in the field of organic fertilizer granulation, and its unique granulation characteristics make it highly favored.
The working principle of a disc granulator is based on the movement of materials on a rotating disc. When the disk begins to rotate, the material gradually gathers at the edge of the disk under the combined action of centrifugal force, frictional force, and gravity. As the disk continues to rotate, the material keeps rolling, and the newly added material continues to adhere to the existing small particles, gradually growing and forming like a snowball.
This granulation method produces organic fertilizer particles with a rounded shape and relatively uniform size. Round particles have obvious advantages in the fertilization process, as they can pass through the fertilization equipment more smoothly and reduce the possibility of clogging. And it is more evenly distributed in the soil, which is conducive to the balanced absorption of nutrients by crop roots.
The structure of the disc granulator is relatively simple, which not only reduces the manufacturing cost of the equipment, but also makes operation and maintenance convenient. For many small and medium-sized organic fertilizer production enterprises, lower investment costs and easy to master operating techniques greatly reduce the production threshold. Operators can easily adjust parameters such as the rotation speed of the disc, the speed of material addition, and humidity, thereby accurately controlling the size and strength of fertilizer particles. For example, increasing the disk speed appropriately can make the material move more vigorously on the disk, which helps to form smaller particles; Increasing the humidity of the material enhances the viscosity between particles, resulting in higher particle strength of the produced fertilizer.
In addition, the disc granulator has strong adaptability to raw materials. Whether it is animal manure, crop straw or other organic materials, as long as they are properly pretreated, they can be smoothly granulated in a disc granulator. This makes enterprises more flexible in raw material selection and able to fully utilize local resource advantages for organic fertilizer production.
The disc granulator occupies an important position in the field of organic fertilizer granulation due to its classic granulation method, good particle characteristics, simple structure, and wide adaptability to raw materials, providing reliable guarantee for the production of high-quality and uniform organic fertilizers.
