[0002] Wear-resistant liners are used to protect the mill cylinder from direct impact and friction from grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the crushing effect of the grinding media on the materials, thereby improving the grinding efficiency of the mill, increasing output, and reducing metal consumption.

[0003] Existing wear-resistant liners require the entire inner liner to be replaced during subsequent replacement. However, in daily use, different parts of the liner often show different degrees of wear, making complete replacement wasteful of resources. Furthermore, segmented installation and disassembly are not possible. Therefore, this utility model proposes a wear-resistant liner for ball mills that is easy to replace. Utility Model Content

[0007] As a further technical solution of this utility model, the cylinder and the annular plate are connected by mounting bolts and threaded holes, the number of threaded holes being twice the number of mounting bolts, and the two being compatible.

[0008] As a further technical solution of this utility model, the wear-resistant liner and the cylinder are connected by a replacement component. The number of wear-resistant liners is several groups and they are arranged in an array. Wear-resistant blocks are provided on the outside of the replacement component.

[0009] As a further technical solution of this utility model, the card block and the wear-resistant liner are fixedly connected, the number of card blocks is equal to the number of wear-resistant liners, the auxiliary groove is a rectangular structure, the positioning groove is a flat arc-shaped structure, and the auxiliary groove and the positioning groove are connected.

[0010] As a further technical solution of this utility model, the number of card slots is equal to the number of auxiliary slots, and the two are compatible with each other. The connecting slot is a cylindrical structure, and the number of connecting slots is several groups arranged in an array. The connecting slots are connected to the moving slots, and the moving slots are connected to the card slots.

[0011] As a further technical solution of this utility model, the linkage rod and the connecting groove are adapted to each other, the hand-held block and the linkage rod are fixedly connected, the hand-held block has a "convex" structure, the limiting block and the linkage rod are fixedly connected, the linkage rod is in several groups and is distributed in an array, the limiting block has an arc-shaped structure, and the limiting block is adapted to both the moving groove and the positioning groove.

[0012] This invention provides a wear-resistant liner for ball mills that is easy to replace. Compared with the prior art, it has the following advantages:

[0013] This design presents an easily replaceable wear-resistant liner for ball mills. A replacement assembly is installed between the cylinder and the wear-resistant liner. When the wear-resistant liner needs to be disassembled, the annular plate is removed, and the hand-held blocks on both sides of the wear-resistant liner are pulled. This causes the two sets of hand-held blocks to move the linkage rods along the inside of the connecting groove, simultaneously moving all the limit blocks in the same row along the moving groove and positioning groove. This causes the limit blocks to disengage from the positioning groove and enter the auxiliary groove. Then, the wear-resistant liner can be pulled outwards using a clamping tool, causing the locking blocks to disengage from the locking groove, thus allowing for the disassembly of the wear-resistant liner. The design is simple and easy to operate. Through the segmented assembly of the wear-resistant liner, targeted disassembly and installation of wear-resistant liners in different areas are achieved, effectively improving the efficiency of wear-resistant liner use and replacement.

[0023] Please see Figure 1-7 This utility model provides a technical solution for a wear-resistant liner for a ball mill that is easy to replace: A wear-resistant liner for a ball mill that is easy to replace includes a cylinder 1, an annular plate 2 is provided on the outer side of the cylinder 1, threaded holes 21 are provided on both the annular plate 2 and the outer side of the cylinder 1, mounting bolts 22 are provided inside the threaded holes 21, a wear-resistant liner 3 is provided inside the cylinder 1, a groove 31 is provided at the edge of the wear-resistant liner 3, and a replacement component 4 is provided between the cylinder 1 and the wear-resistant liner 3;

[0024] The replacement component 4 includes a locking block 41. The outer side of the locking block 41 is provided with an auxiliary groove 42 and a positioning groove 43. The inside of the cylinder 1 is provided with a locking groove 44 and a connecting groove 45. The inside of the connecting groove 45 is provided with a moving groove 46. The inside of the connecting groove 45 is provided with a linkage rod 47. The outside of the linkage rod 47 is provided with a hand-held block 48 and a limiting block 49.

[0025] Please see Figure 1-2 and Figure 5The cylinder 1 and the annular plate 2 are connected by mounting bolts 22 and threaded holes 21. The number of threaded holes 21 is twice the number of mounting bolts 22, and the two are compatible, which facilitates the installation between the cylinder 1 and the annular plate 2.

[0026] Please see Figure 2-7 The wear-resistant liner 3 is connected to the cylinder 1 through a replacement component 4. The number of wear-resistant liners 3 is several groups and they are arranged in an array. Wear-resistant blocks are provided on the outside of the replacement component 4. The locking blocks 41 are fixedly connected to the wear-resistant liners 3. The number of locking blocks 41 is equal to the number of wear-resistant liners 3. The auxiliary groove 42 is a rectangular structure and the positioning groove 43 is a flat arc structure. The auxiliary groove 42 and the positioning groove 43 are connected, which facilitates the subsequent installation and placement of the wear-resistant liners 3.

[0027] Please see Figure 2-7 The number of slots 44 is equal to the number of auxiliary slots 42, and the two are compatible. The connecting slot 45 is a cylindrical structure, and there are several groups of connecting slots 45 arranged in an array. The connecting slots 45 are connected to the moving slots 46, and the moving slots 46 are connected to the slots 44. The linkage rod 47 is compatible with the connecting slots 45. The hand-held block 48 is fixedly connected to the linkage rod 47. The hand-held block 48 has a "convex" structure. The limiting block 49 is fixedly connected to the linkage rod 47.

[0028] The working principle of this utility model is as follows: When the wear-resistant liner 3 needs to be disassembled, the mounting bolt 22 is rotated out of the threaded hole 21 to disassemble the annular plate 2. Then, the single and multiple sets of wear-resistant liners 3 that need to be disassembled inside the cylinder 1 are rotated to the bottom of the cylinder 1. By pulling the hand blocks 48 on both sides of the wear-resistant liner 3, the two sets of hand blocks 48 respectively drive the linkage rod 47 to move along the inside of the connecting groove 45, and at the same time drive all the limit blocks 49 in the same row to move along the moving groove 46 and the positioning groove 4. The wear-resistant liner 3 moves inside, causing the limiting block 49 to disengage from the positioning groove 43 and enter the auxiliary groove 42. Then, by inserting a clamping tool or pliers into the grooves 31 on both sides, the wear-resistant liner 3 to be disassembled is pulled outward, causing the locking block 41 to disengage from the groove 44. Then, a new wear-resistant liner 3 is replaced, so that the locking block 41 is inserted into the groove 44, resetting the two sets of linkage rods 47. At the same time, the limiting block 49 will be inserted into the positioning groove 43 again, thereby limiting and fixing the wear-resistant liner 3.

[0029] It should be noted that this design has a simple structure and is easy to operate. Through the segmented assembly of the wear-resistant liner 3, the targeted disassembly and installation of the wear-resistant liner 3 in different areas can be achieved, which effectively improves the efficiency of use and replacement of the wear-resistant liner 3.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
