<p>According to the invention, certain wear plates (12, 17) of the ball (2) mill (1) form a step towards the axis of rotation (8) of the shell (3), at least one face of which is provided with lateral ball races (14, 18). The plane of symmetry of these lateral races (14, 18) forms an angle () equal to at least 15 DEG with the transverse plane of the shell (3). A preferred wear plate (12) with lateral races (14) has a middle shoulder (13), on the two sides of which a plurality of races (14) are recessed at different heights. <IMAGE></p> |
