PURPOSE: An air-floatable belt conveyor is provided to properly maintain a floating level of a conveyor belt part regardless of load by automatically controlling air volume according to the load of a continuous belt. CONSTITUTION: An air-floatable belt conveyor(100) comprises a continuous belt(20), a driving motor(13), a belt support part(30), a blower(40), and an air volume control part. The continuous belt is wound on a pair of pulleys(11,12). The driving motor is installed in one of the pair of pulleys. The belt support part comprises a support body, an air duct, and a nozzle. The air duct supplies air to the continuous belt to float the continuous belt. The blower is connected to the air duct and supplies air to the air duct. The air volume control part detects the load of the continuous belt on which objects are dropped and controls the discharged air volume of the blower according to the detected load.
