AI Technical Summary
Traditional mill end liners have poor impact and wear resistance and are prone to cracking and breakage, which affects the operating rate of the mill equipment and shortens its service life.
A mill end liner is designed, in which a convex ball-carrying portion is provided in the middle section of the lifting rib. The ball-carrying portion has an inclined ball-facing surface and a protrusion. The inclined angle of the ball-facing surface is 30° to 45°, which enhances wear resistance and facilitates the falling of grinding balls to avoid excessive wear.
It improves the wear resistance and impact resistance of the mill end liner, extends its service life, reduces the contact wear between the lifting ribs and the grinding balls, and improves the operating stability of the mill equipment.

[0013] Further, the middle part of the lifting rib is provided with a fixing hole penetrating through the lining plate.
[0014] Technical effects and advantages of the utility model:
[0015] The utility model provides a raised ball-carrying portion in the direction of rotation of the lifting rib, the ball-carrying portion has an inclined ball-facing surface, and a protrusion is provided in the middle of the ball-carrying portion. The wear resistance effect is enhanced by the protrusion, and the inclined angle of the ball-facing surface is 30° to 45°. During use, the ball-facing surface lifts the grinding balls in the ball mill and contacts the lifting rib. The setting of the ball-facing surface being inclined at a certain angle makes it easier for the lifted grinding balls to fall, avoids excessive wear between the lifting rib and the grinding balls, and thus enhances the service life of the end liner of the mill.
