A sludge drying apparatus is provided to prevent air pollution by dust gas generated in the drying procedure by discharging the dust gas after filtering through the cyclone and back filter. A sludge drying apparatus comprises a drier(100) in which slug and sludge are put into and dried, a burner part(110) supplying hot air to the drier, a cyclone(120) which drops the sludge, which is included in the exhaust air from the drier, with the centrifugal force, and a back filter(130) which filters fine dust of the primarily filtered exhaust air.
