ABSTRACT:
Replaceable liner for the discharge assembly of a rotary grinding mill or the like is disclosed, in the preferred embodiment, as including first and second, self-supporting box members. The first box member includes closed sides, bottom, and second end, and includes an open top and first end. The second box member includes closed sides, top, and bottom, and includes open ends. When the grate is removed from the first discharge casting, the second box member can be inserted within the first discharge casting and moved into the second and third discharge castings. Then the first box member can be placed within the first discharge casting. Thus, when the grate is attached to the first discharge casting, the first and second box members will be captured within the first and second discharge castings. Reinforcing members are embedded in the box members for retaining their shape. Furthermore, the angle between the inside surfaces of the top and sides of the box members is perpendicular to increase the volume of the ground material path and for increasing wear.
