A rotary feeder for granulated bulk material includes a housing with a rotor by which the bulk material is transported from the supply well to the discharge well via a plurality of compartments. Arranged at the inner wall of the housing is a pocket-like recess which is defined by a pre-stripping edge and by a V-shaped stripping edge extending from the pre-stripping edge. The pocket-like recess is V-shaped, with its tip pointing in rotational direction of the rotor. A deflector partly fills the recess to substantially free the tip of the recess from bulk material grains and includes a tip pointing opposite to the rotational direction of the rotor, sides converging in this tip and ending at a distance from the stripping edge by about the means grain diameter of the bulk material, and a base extending in the generated cylindrical surface defined by the radial end faces of the rotor.
