The casing (1) encloses a grille (3) in the shape of a truncated cone whose small base is directed downwards. The upper part of the body has an opening (2) for the introduction of the product. The central part of the grille is connected to a funnel (4) by a duct (5) through which particles which have not passed through the grill are evacuated. The particles which have passed through the grille are collected on a truncated surface (6) whose small base, extending downwards, is connected to an exhaust duct (7). The casing is agitated in a circular movement by an unbalanced motor (8) which cause the particles to rotate around the smallest diameter circumferences. The product at the grill periphery is diverted by a cone (9) located above the grill whose base diameter is less than the grille major diameter. The product can be divided and guided by ribs (10) on this cone surface.
