The Complete Granulation Process
The roller shaft of the flat die granulator rotates with its main shaft during operation. At the same time, the material is squeezed by friction to form particles in the die hole. With the continuous movement of the pressure roller, the fertilizer particles are continuously formed and extruded from the bottom of the die roller. When the material is extruded to a certain length, the cutter at the bottom of the die cuts the pellets. When falling on the bottom plate of the scraper, the fertilizer granules are conveyed out of the flat die granulator by the scraper.
