What Is Particle Size Screening Effect of Disc Granulation?
A very important feature of the disc organic fertilizer granulator is the ability to classify the particle size. In layman’s terms, when using a disc granulator, there is a fixed requirement for the size of the product. Because the friction coefficient of the feed powder and the smaller particles is large, the bottom silo where materials are often tumbling in the disk can rise to the highest position of the turntable before falling. The larger agglomerates are often on the surface of the bed, and the flow path is relatively short. When operating continuously, the largest agglomerate or product with the required particle size will overflow out of the disk from the surrounding baffle, while the smaller agglomerates and fine powder will remain in the disk and continue to increase the particle size until the required particle size is reached.
The screening function of disc type pelletizer is an important feature of its own, and this feature plays an important role in industrial production. In many occasions, the required products can be obtained directly through this function, without too many subsequent steps, such as sieving. If the particle size requirements of the product are very strict, then as long as the rotating comb screen discharging machine is assembled on the disc granulation drum, a more uniform particle size product can be obtained.
