PROBLEM TO BE SOLVED: To provide a dust exhausting apparatus and method in an asphalt plant, which effectively prevent dust leakage from occurring from a plant main body. ! SOLUTION: A dust exhausting apparatus is provided, in which: static-pressure meters 23, 28 and 31, and exhaust ducts 24, 29 and 32 are respectively provided at each of dust generation sources in a plant body 4; air-flow adjustment dampers 25, 30 and 33 are respectively included in each of the exhaust ducts 24, 29 and 32; and further, a static-pressure/air-flow controller 35 is provided, for controlling an aperture of each of the air-flow adjustment dampers 25, 30 and 33, on the basis of static-pressure values detected by the static-pressure meters 23, 28 and 31. The static-pressure/air-flow controller 35 controls the aperture of each of the air-flow adjustment dampers 25, 30 and 33 so that static pressure around each of the dust generation sources is set slightly lower than the atmospheric pressure. !
