Claims

[Claims for Utility Model Registration] (1) A tube-shaped shell portion that is driven and rotated;
It has a ball built-in part surrounded by head parts fixed to both ends of the shell part, and the crushed raw material fed into the ball built-in part is crushed by the rolling of the built-in balls. In a ball mill for grinding, the liner is fitted into a corner formed between a shell liner laid on the inner wall surface of the shell portion and a head liner laid on the inner wall surface of the head portion, and the liner has a surface facing the ball built-in portion. A liner for a ball mill, characterized in that the liner has a surface that approximates the surface of the ball so that the ball can easily adhere to the ball. (2) The ball mill liner according to claim 1, wherein the surface facing the built-in part of the ball mill is a curved surface having a radius of curvature greater than the radius of the ball. (3) The liner for a ball mill according to item 2, wherein the surface facing the built-in part of the ball mill is a flat surface, and the angle that the surface forms with the shell liner and the angle with the head liner are obtuse angles.
