[0030] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0031] Example

[0032] A liner structure to prevent material accumulation, refer to Figure 1 and Figure 2 , including a screen plate 1, a lining plate 2, an arc groove 20, an inclined groove 21 and a lining strip 22. The lining plate 2 is arranged on the inner surface of the screen plate 1. As the screen plate 1 rotates, the arc groove 20 and the inclined groove 21 are opened on one side of the lining plate 2, so that one side of the lining plate 2 is relatively smooth and it is not easy to accumulate materials. The lining strip 22 is fixed to one side of the lining plate 2 by welding, which can improve the grinding efficiency of the ball mill, thereby achieving the purpose that the lining plate structure can effectively prevent the material from being blocked.

[0033] Reference Figure 2There are one hundred and ninety-two lining blocks 2, and every thirty-two lining blocks 2 are distributed in a ring shape, so that the lining blocks 2 can cover the entire inner surface of the screen plate 1.

[0034] Reference Figure 2 There are five hundred and seventy-six lining strips 22, and every three lining strips 22 are distributed at equal intervals, so that the lining strips 22 can effectively improve the grinding efficiency of the ball mill.

[0035] Reference Figure 2 The inner surfaces of the arc groove 20 and the inclined groove 21 are jointly provided with a groove 23, and when the groove 23 rotates downward, the ground material can be collected.

[0036] Reference Figure 3 The interior of the lining block 2 is provided with a screw 31, a nut 30, a screw groove 33 and a sieve hole 32. A nut 30 is welded and fixed to one end of the screw 31. A screw groove 33 is opened on one side of the lining block 2 for fixing the screw 31 and the sieve plate 1. The sieve hole 32 is opened on one side of the lining block 2 for collecting the ground material, thereby achieving the purpose of convenient disassembly of the lining plate structure.

[0037] Reference Figure 3 A fixing groove 34 is opened on one side of the lining block 2, so that the nut 30 can be limited in the fixing groove 34 to reduce wear.

[0038] Reference Figure 1 and 3 The outer surface of the screen plate 1 is provided with a plurality of screen slots 3, which can discharge the ground material in cooperation with the screen holes 32. The screen holes 32 are linearly distributed on one side of the lining block 2, so that the screen holes 32 can cooperate with the grooves 23 to collect the ground material.

[0039] The implementation principle of the embodiment of the present application is as follows: when the liner structure is used in a ball mill, the material and the grinding balls in the ball mill will be ground on the liner strip 22 on one side of the liner plate 2 as it rotates, and due to the arc groove 20 and the inclined groove 21 on one side of the liner plate 2, one side of the liner plate 2 is relatively smooth, and it is not easy for the material and the grinding balls to get stuck, thereby preventing the material from piling up, improving the grinding efficiency of the ball mill, and thus achieving the purpose of the liner structure being able to effectively prevent the material from getting stuck;

[0040] When the liner structure needs to be disassembled in the ball mill, the nut 30 in the fixed groove 34 on one side of the liner plate 2 is rotated so that the screw 31 can be disengaged from the screw groove 33, thereby releasing the limit fixation with the liner plate 2 and taking it out for disassembly. The sieve hole 32 cooperates with the groove 23 to allow the material to be sieved out, and the ground material can be collected, thereby achieving the purpose of convenient disassembly of the liner structure.
