1. Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing. The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller press granulator. https://www.organic-fertilizer-machinery.com/fertilizer-granulator-machine-series/double-roller-press-granulator.html
2. Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate. Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles. This method is used in https://www.organic-fertilizer-machinery.com/fertilizer-granulator-machine-series/disc-granulator.html disc granulator and rotary drum granulator. https://www.organic-fertilizer-machinery.com/fertilizer-granulator-machine-series/rotary-drum-granulator.html
