The spray fluidized bed granulator uses gas to fluidize the solid particle group, and the liquid is atomized and sprayed in the fluidized material layer at the same time to complete heat and mass transfer, and the cladding and growth of the material on the particle surface. The material is discharged after reaching the required particle size and moisture.
The spray fluidized bed granulator uses process gas to fluidize the solid particle group, while the process material liquid is atomized and sprayed in the fluidized material layer. In this process, the heat and mass transfer and the cladding and growth of the material on the particle surface are completed at the same time.. After the material reaches the required particle size and moisture, it is discharged out of the spray fluidized bed granulator in the fluidized state.
