Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill lining plates, in particular to an anti-falling structure of a ball mill lining plate. Background Art

[0002] Ball mill is mainly suitable for re-grinding and fine crushing of ore materials after coarse crushing. The liner of ball mill is mainly used to protect the cylinder body, so that the cylinder body is protected from the impact and friction of the grinding body and materials. At the same time, when the grinding body is brought to a certain height, it is thrown down due to its own gravity. The falling grinding body crushes the materials in the cylinder of the ball mill like a projectile.

[0003] However, most of the existing ball mill liners are fixed with bolts and nuts, which is not convenient for replacement and maintenance of the liners. In addition, the vibration generated by the grinding body hitting the liner during the operation of the ball mill may cause the bolts and nuts to loosen, making the connection between the liner and the cylinder easy to loosen and fall off. When the liner falls into the inside of the cylinder, it causes damage to the inside of the cylinder, thereby reducing the service life of the ball mill. Utility Model Content

[0004] The purpose of the utility model is to provide a ball mill liner anti-falling structure, which reduces the deformation groove by inserting the plug-in column into the fixed sleeve, drives the conical limit block to engage with the annular limit groove, and solves the existing problem of inconvenience in replacing and maintaining the liner and easy falling of the liner by cooperating with the threaded column, the cylindrical block and the conical groove.

Then, the fixing stud 15 is threadedly engaged with the positioning ring 14 to further improve the fixing effect of the arc lining 2. Specific embodiment 2:

[0039] Based on the specific embodiment 1, the difference of this embodiment is that:

[0040] like Figure 4 , 6As shown, a cylindrical block 10 is slidably fitted in the top of the annular limit groove 401, and a conical groove 11 is opened at the bottom of the cylindrical block 10 for slidingly fitting with a conical limit block 6. A threaded column 12 is rotatably connected to the top of the cylindrical block 10, and the top of the threaded column 12 penetrates to the outside of the fixed sleeve 4 and is threadedly connected to each other; the cylindrical block 10 is driven to move toward the plug-in column 5 by rotating the threaded column 12, so that the conical limit block 6 is located in the conical groove 11 and is squeezed and fitted with the inner wall of the conical groove 11, so that the deformation groove 7 shrinks, driving the conical limit block 6 to disengage from the engagement with the annular limit groove 401, thereby facilitating the replacement and maintenance of the liner.
