To provide a fine particle concentrating and classifying mechanism and its apparatus recovering large particles without containing small particles.
Flow passage structure is used having at least one branch point 17 on the side face of the flow passage 11, and at least one branch passage 12 connected to the flow passage at the branch point and having at least one of scales such as length, width, depth or diameter properly adjusted. Fluid is introduced to the flow passage to be separated into fluid containing particles and fluid containing no particles, and at the branch point, particles of a certain size or larger are made not to enter the branch passage, and particles of a certain size or smaller are made not to enter the downstream side of the branch passage. Thus, the fluid containing all of the introduced particles of a certain size or smaller, or the fluid containing no particles of a certain size or larger, is recovered from the branch passage, to recover the fluid with increased concentration of particles of a certain size or larger from the downstream side of the passage.
