A grate support element for supporting a grate of an open-ended grinding mill that includes an outer perimeter section, an inner section, and at least one vane extending between the outer perimeter section and the inner section. The grate support element further includes a mounting flange at the outer perimeter of the grate support element configured to enable mounting of the grate support element to a shell of the grinding mill at an area of the shell not intruding to the grinding mill volume. The mounting flange extends outwards from the middle of the cross section of the grinding mill.
