<p>A mill liner for a dry autogenous mill includes low profile end liner elements (12, 15) at the ends of the mill incorporating radial ribs (19, 20, 21) with proper height to provide significantly improved mill performance without sacrificing the grinding efficiency. Shell liner elements (40 or 44) are also provided with lifter bars (41 or 43) as an integral part thereof to simplify maintenance work as well as reduce scrap losses. For the larger size mills, the shell liners are preferably made of a three piece design, a middle section (44) and two identical end sections (45), thus permitting the middle section which bears most of the wear to be replaced without having to replace the two end sections. </p> |
