A liner assembly for the cylindrical shell (12) of an ore grinding machine, which is arranged in a series of axial sections (11), each being made up of individual liner segments (13-16) that cover substantially the entirety of the inner cylindrical surface of the shell. Each axial section is generally annular in configuration and is formed with a plurality of ramp-like surfaces that extend circumferentially and define sequential steps, with the lowest point of one ramp-like surface adjacent the highest point of another. The ramp-like surfaces of each axial section are circumferentially staggered with respect to the ramp-like surfaces of an adjacent annular section, resulting in increased grinding efficieny of the grinding machine. |
