How are the granules of the drum granulator made?
The principle of the drum granulator is that the material relies on the surface tension, the right amount of liquid phase, the squeezing force generated by the rolling of the material, and the material is in the correct direction of movement in the granulator with small particles as the core, and it is bonded during the rolling. Into a ball.
When working, after the powdered raw materials are added to the drum with a certain slope and slowly rotating from the feeding building, the materials once rotated upwards under the drive of the internal copy board. When they reach a certain height, under the action of gravity and inertial force, the materials move along The arc-shaped track falls to make the material complete the rolling motion required for granulation. The inside of the drum granulator is sprayed on the rolling material layer by steam or water, so that the surface of the fine particles and other fine powders adhere and agglomerate into granules. The material is granulated in the granulation zone, and then passes over the annular material ring to enter the polishing zone. In the polishing zone, the particles are aged and polished, and after the fine particles grow up, they are discharged from the outlet of the drum.
