PROBLEM TO BE SOLVED: To provide an aggregate fine powder removing device improving a fine powder removing efficiency by forming an aggregate transfer surface in a simple structure and also effectively spraying the air from downward and the high-pressure air from upward to the aggregate. SOLUTION: The aggregate K charged from an aggregate charge part 21 is transferred toward an aggregate discharge part 22 on the aggregate transfer surface 20 by applying vibration to a main body part 1, and the fine powder contained in the aggregate is blown away and removed by simultaneously spraying the air from downward jetted from an air hole 23 and the high-pressure air from upward jetted from an air nozzle 5 to the aggregate transferred on the transfer surface.
