To provide an apparatus for selecting a particulate matter wherein smooth and highly efficient selection is performed without obstructing action of selection caused by mixing a hardly rolling particulate matter selected and removed into a selected and easily rolling particulate matter and retaining a particulate matter on the inner face of a shell where the action of selection is performed.

In an apparatus for selecting a particulate matter wherein a funnel-like shell 1 is rotated under inclined condition and the particulate matter fed on the inner face of the shell 1 is selected by its difference in easiness of rolling, a guide means 5 for guiding movement of the particulate matter remaining on the inner face of the shell 1 is provided. In addition, a separating means 62 for separating the particulate matter discharged from the outer peripheral edge of the shell 1 in accordance with the position of discharging in the circumferential direction is provided.
