The utility model relates to a granulator. The discharging device comprises a mounting frame and a discharging roller mounted on the mounting frame, a discharge hole is formed in the discharge roller;the discharging roller is communicated with a feeding device; a driving device is connected to the discharging roller, a material receiving device is arranged below the discharging roller, a discharging shaft is arranged in the discharging roller, a material storage bin is arranged in the discharging shaft, a groove is formed in the discharging shaft in a sunken mode, a cover plate is arranged onthe groove, a plurality of through holes are formed in the cover plate, an elastic piece is arranged in the groove, and a sealing piece is arranged on the cover plate. The elastic piece abuts againstthe cover plate; the through holes are formed in the cover plate, so that materials flowing out of the through holes are not prone to being retained in the discharging roller or flowing into the abutting position of the discharging roller and the cover plate, waste of the materials is avoided, further, the materials falling into the discharging roller are not prone to being solidified and blockedin the discharging holes after being separated from the heat preservation environment, normal discharging of the discharging roller is not affected, and the later cleaning cost is reduced.
