Abstract: A grate support element for supporting a grate of an open-ended grinding mill comprises 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 comprises 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.

Abstract: An open-ended grinding mill (1) includes a drum (2) including a cylindrical shell (3), wherein the longitudinal axis (4) of the drum is arranged in a substantially horizontal position in a use position of the grinding mill (1). The drum (2) includes a first end (5) at the feed end of the shell and a second end (6) at the discharge end of the shell. The grinding mill further includes a bearing (8) supporting the drum at the second end, and a support structure (9) to connect the drum (2) to the bearing (8). The support structure is configured to provide a wall external to the shell, whereby the shell and the support structure provide a double-wall structure separating the bearing from the inside of the drum.
