An apparatus for sorting blocks made of concrete or concrete-like material, in particular paving slabs, having a vibration arrangement and a sorting arrangement which slopes with respect to the horizontal, has an entry part for the blocks which are to be sorted and a sorting part, which has at least one collecting channel running in the conveying direction. The collecting channel has a central part and two lateral run-on surfaces arranged thereon, the width of the central part corresponding at least approximately to one of the two shorter edge lengths of the blocks which are to be sorted. The run-on surfaces are provided with stop elements, the stop elements on one run-on surface being offset in the longitudinal direction with respect to the stop elements on the other run-on surface.
