A grate basket for hammer crushers composed of at least two segments respectively made up of a plurality of parallel grate basket walls in the form of ring sections arranged coaxially with regard to the rotor and of grate bars extending parallel to the rotor axis while being exchangeably connected to the grate basket walls interconnected by longitudinal connecting elements. The grate basket is characterized primarily in that the grate basket walls are respectively divided into a base wall held by the longitudinal connecting elements and into a bar carrier which is adapted to receive the grate bars and which is secured against rotation in circumferential direction and against displacement in axial direction, the grate bar carrier being exchangeably connected to the inner surface of the base wall.
