PROBLEM TO BE SOLVED: To make a fine powder removal apparatus capable of improving the regeneration efficiency of washing particles and improve the quality of the regenerated product by promoting separation of washing particles from the fine particles and preventing re-adhesion of the particles to the fine powder. SOLUTION: This fine powder removal apparatus comprises a washing tank 1 forming a closed space, a suction port 2 formed in an upper part of the washing tank, a flow-in port 3 formed in the lowest part of the washing tank, a pressure difference supply means 9 for generating air current between the flow-in port and the suction port owing to the pressure difference, and a mesh 4 for parting the suction side and the flow-in side in the washing tank. The mesh is downward projected to the flow toward the suction port from the flow-in port and particles are carried with a high speed air current in the washing tank flowing upward from the flow-in port to the suction port and come into collision against the mesh, and owing to the impact, the fine powder is parted from the particles and only the fine powder passes through the mesh and is discharged through the suction port.
