The invention relates to a device (S) for separating fragments of particles (p) from said particles, including a floor (1) that is arranged so as to receive said particles and said fragments and is connected to a first means (2) that is arranged so as to animate said floor (1) with a vibrating movement, said floor (1) being bored with openings (3) in order to allow said fragments, but not said particles, to pass through said openings (3), and a ceiling (7) arranged substantially parallel to said floor (1). The device also includes a second means (8) arranged so as to move said ceiling (7) between a first position in which it is located at a distance (d) from the floor (1) and a second position in which it is in contact with the floor (1) so that particle fragments which are stuck in said openings (3) are ejected therefrom. |
