The powder granule in the container (fluidization)appear in the state of fluidization. It is preheated and mixed with chen and heated air. At the same time the solution of adhesive solvent is fogged and sprayed into the container. It makes the some particles become granulating that contains adhesive. Being of unceasing dry through hot air, the moisture in the granulation is evaporated and the adhesive is solidification. The process is carried out continuously. Finally it forms ideal, uniform and Porous granules. Improve fluidity and reduce dust flying by powder granulation. Improve its solubility by powder granulation. Mixing-granulation-drying completes one-step granulation in one machine. Antistatic filter material is used to ensure safe operation of the equipment.
