The disc granulator is a classic and unique presence in the field of organic fertilizer granulation, and its granulation method is full of clever application of physical laws.
When the disc granulator starts, the disc begins to slowly rotate. The pre treated organic fertilizer material is evenly distributed onto a rotating disc. Under the combined action of centrifugal force, frictional force, and gravity, materials begin to gather at the edge of the disc. As the disc continues to rotate, the material keeps rolling, just like a lively ‘dance’.
During this process, the newly added material continuously adheres to the existing small particles, like rolling snowballs, and the particles gradually grow and form. In order to better shape the particles, sometimes an appropriate amount of binder solution is sprayed into the disc. Adhesive is like a magical glue, enhancing the viscosity between materials and accelerating the aggregation of particles.
The unique granulation method of the disc granulator creates its distinctive characteristics in producing granules. The organic fertilizer particles produced have a rounded shape and relatively uniform size. Round particles have obvious advantages in the fertilization process, as they can pass through various fertilization equipment more smoothly and reduce the problem of clogging. And it is more evenly distributed in the soil, which is conducive to the balanced absorption of nutrients by crop roots.
This granulation method also has a certain degree of flexibility. Operators can precisely control the size and strength of fertilizer particles by adjusting parameters such as the rotation speed of the disc, the rate of material addition, and the amount of binder sprayed. 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 spraying amount of adhesive can improve the strength of particles.
The granulation method of the disc granulator is simple and intuitive, and the equipment structure is relatively simple. This not only reduces the manufacturing cost of the equipment, but also makes operation and maintenance more convenient. For many small and medium-sized organic fertilizer production enterprises, it is a cost-effective choice. With this unique granulation method, the disc granulator has always occupied an important place in the field of organic fertilizer production.
