In the production of organic fertilizer granulation, there are three types: agglomerate granulator, wet granulator, and extrusion granulator. The agglomerate granulator includes a disc granulator, a stranded granulator, and a wet granulator. The new type stirring tooth granulator, extrusion granulator has a pair of roll extrusion granulator. In most cases, the production of organic fertilizers uses a disc granulator or a new type of stirring tooth granulator. The roller extrusion making pellets machine is suitable for granulating materials that are too loose and difficult to granulate.
The roller extrusion granulation machine does not need to heat or humidify the material, save investment, save energy, can adapt to the heat-sensitive material, no waste water or waste gas is discharged in the production, and will not pollute the environment. The extrusion granulation process flow short, simple operation, easy to complete production automation, improve production efficiency, no special requirements for the nature and particle size distribution of the material, high hardness, no segregation, and no agglomeration.
