A granulating, fluidizing and drying system is provided with a vibration fluidizing machine, a granulating machine, a cyclone separator, a water film dust remover, a crusher, a heating device and a cooling device. A ventilation area on a bed plate of the vibration fluidizing machine is formed by connecting round unit ventilation areas which are arranged in a line. A screening device is arranged at the tail end of the bed plate, air holes at the middle square positions of the unit ventilation areas on the bed plate are straight holes, and air holes on four bow-shaped parts of the unit ventilation areas on the bed plate are scale holes. The air outlet direction of the scale holes on two bow-shaped parts on the front part in each unit ventilation area is towards a box wall, and the air outlet direction of the scale holes on two bow-shaped parts on the rear part in each unit ventilation area is towards the connection position of two unit ventilation areas. Air inlet tubes corresponding to the unit ventilation areas one by one are arranged in an air chamber. The granulating, fluidizing and drying system can integrally achieve granulation, drying, cooling and screening, has high efficiency, treats exhausted tail gas, and is favorable for environment protection. By means of a special shape of the bed plate and the distribution of the air holes, fluidization of the vibration fluidizing machine is stable and free of dead corners.
