The disc granulator is widely used in industrial production, and its unique equipment principle endows it with many application advantages.
The operation of the disc granulator is based on simple yet sophisticated physical principles. The main body of the device is a tilted disc that is driven by a motor to perform uniform circular motion. The powdered material is conveyed to the rotating disc through the feeding port.
When the disk rotates, the material is subjected to a dual effect of centrifugal force and frictional force. Centrifugal force drives the material to move towards the edge of the disc, while frictional force carries the animal material upwards along the inner wall of the disc. The interaction between these two forces causes the material to form a continuous cyclic motion trajectory on the disc.
The addition of binders is a crucial step in achieving particle shaping during material movement. By installing a nozzle above the disc, the adhesive is evenly sprayed onto the material. The interaction between binder molecules and the surface of material particles reduces the repulsive force between particles, increases the attractive force between particles, and causes small powder particles to start to bond with each other, forming tiny aggregates.
As the disk continues to rotate, these aggregates continuously adsorb the surrounding powdery materials through rolling and collision, gradually growing into larger particles. In this process, the rotation of the disc plays a role in stirring and mixing, ensuring that all particles can grow uniformly, thereby ensuring that the size and shape of the particles are relatively consistent.
The principle of the disc granulator brings significant application advantages. Firstly, it has high universality. It can handle various types of powdered materials with different properties, whether organic or inorganic, and can achieve granulation through appropriate binders. Secondly, the particles produced by the disc granulator have regular shapes, smooth surfaces, good flowability and dispersibility, which is particularly important for industries that require high product appearance and physical properties.
Furthermore, the device is relatively easy to operate and has lower maintenance costs. Its structure is relatively simple, easy to install and debug. Moreover, by adjusting parameters such as the rotation speed, tilt angle, and adhesive spraying amount of the disc, the size, shape, and yield of particles can be flexibly controlled to meet different production needs.
The disc granulator, with its unique equipment principle and many application advantages, plays an important role in multiple industries such as fertilizers, chemicals, and feed, contributing to improving production efficiency and product quality.
