The invention discloses a drying device for ceramic particles. The drying device comprises a shell forming a drying tunnel, a heater and a conveying belt. The continuous conveying belt is erected in the shell. The two sides of the shell are provided with a feeding port and a discharging port respectively. Ventilation holes are formed in the conveying belt. The drying tunnel is divided into a radiation drying section and a cooling section. The heater is installed below the radiation drying section, and a first air inlet pipe is installed in the position, below the heater, of the shell. A double-layer exhaust pipe is arranged between the radiation drying section and the cooling section. A second air inlet pipe is arranged below the cooling section. The first air inlet pipe is communicated with an outer pipe, and the second air inlet pipe is communicated with an inner pipe. The input end of the second air inlet pipe and the input end of the first air inlet pipe are communicated with a draught fan. The drying device has the beneficial effects that the ceramic particles are static on the conveying belt, and the collision among the ceramic particles can be effectively avoided.
