Ball mill liners are usually divided into two forms, one is installed on the inner wall of the cylinder of the ball mill, and the other is installed on the inner wall of the cylinder cover of the ball mill, as shown in the existing patent technology: After searching, China Patent Network discloses a wear-resistant ball mill liner (public announcement number CN214210769U). The ball mill liner of this type of device is divided into multiple arc blocks. When in use, it can be fixed to the bottom of the cylinder of the ball mill by plugging and blocking. This installation method is relatively simple and convenient for replacing a worn liner.

[0003] However, there are still some shortcomings in the ball mill liners adopted in the above-mentioned public patents and the existing market: the existing method of assembling the liner and the bottom plate in an integrated manner by plugging and clamping, when it is used in an integrated manner, when it needs to be disassembled, repaired and replaced later, it is impossible to disassemble the damaged parts independently, and the entire part needs to be disassembled before the damaged parts can be taken out, which is a cumbersome operation. To this end, those skilled in the art provide a combined wear-resistant liner to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0024] Please refer to Figure 1-4 As shown, a combined wear-resistant lining includes a tooling disc assembly 1 and multiple groups of lining assemblies 2 which are arranged circumferentially and installed inside the tooling disc assembly 1. The tooling disc assembly 1 and the lining assembly 2 both adopt one of high-chromium cast iron plates or high-manganese steel wear-resistant plates. The top-sealed wear-resistant lining composed of high-chromium cast iron plates or high-manganese steel has good wear resistance, corrosion resistance, firmness and other properties, and can play a long-term protective role.

[0025] The tooling disc assembly 1 includes a tooling disc 11, a flange seat 12 is arranged in the middle of the ring frame of the tooling disc 11, and a plurality of groups of alignment rails 15 are arranged circumferentially along the flange seat 12 inside the ring frame of the tooling disc 11. The lining plate assembly 2 includes a lining plate 21, and a bottom plate surface of the lining plate 21 is provided with an alignment groove 23 corresponding to the alignment rail 15. The alignment rail 15 and the alignment groove 23 are of the same size, and each group of alignment rails 15 and each group of alignment grooves 23 correspond to each other one by one. When the wear-resistant lining of the ball mill is assembled as a whole, the engagement limit of the alignment rail 15 and the alignment groove 23 is used as a limit positioning component, and the plurality of groups of lining plate assemblies 2 are installed one by one in the tooling disc assembly 1 in a circumferential arrangement and installation manner, so that it forms a complete circular lining plate structure.

[0026] An outer toothed disc 13 is provided on the inner wall of the edge of the tooling disc 11, and an inner toothed disc 14 is provided on the inner wall of the center of the tooling disc 11. An outer tooth groove 25 is provided on the outer edge of the lining plate 21, and an inner tooth groove 26 is provided on the inner edge of the lining plate 21. The outer toothed disc 13 and the outer tooth groove 25 are staggered and meshed with each other, and the inner toothed disc 14 and the inner tooth groove 26 are staggered and meshed with each other. When the lining plate assembly 2 and the tooling disc assembly 1 are assembled as a whole, the outer tooth grooves 25 and the inner tooth grooves 26 on the lining plate assembly 2 are staggered and meshed one by one on the outer toothed disc 13 and the inner toothed disc 14 of the tooling disc assembly 1. On the one hand, the accuracy of the integrated assembly is improved, and on the other hand, the contact area between the lining plate assembly 2 and the tooling disc assembly 1 is increased, thereby ensuring the stability of the assembly and avoiding centrifugal loosening of the wear-resistant liner during rotation.

[0027] A positioning screw hole A16 is provided on the track surface of the alignment rail 15, and a positioning screw hole B24 is provided on the bottom of the alignment slot 23. The positioning screw hole A16 and the positioning screw hole B24 overlap and correspond to each other, and the mating ends of the positioning screw hole A16 and the positioning screw hole B24 are matched and screwed with fastening bolts. When multiple sets of lining plate assemblies 2 and tooling disk assemblies 1 are installed one by one, the matching fastening bolts are simultaneously screwed into the positioning screw holes A16 and the positioning screw holes B24, which plays a role in screwing and fixing the integrated combination of the lining plate assembly 2 and the tooling disk assembly 1.

[0028] The upper plate surface of the liner 21 is provided with reinforcing ribs 22, and the reinforcing ribs 22 are an arc-shaped structure, and the reinforcing ribs 22 are arranged in a spiral relative to the lining surface of the liner 21. By arranging the reinforcing ribs 22 arranged in a spiral on the lining surface of the liner assembly 2, on the one hand, it can play the role of reinforcing ribs to improve the firmness and wear resistance of the liner assembly 2, and on the other hand, it can play a propulsion role to assist in pushing the material inside the ball mill when the ball mill rotates.

[0029] The working principle of the utility model is as follows: when the wear-resistant liner of the ball mill is assembled as a whole, the alignment rail 15 and the alignment groove 23 are used to engage and limit, and multiple groups of liner assemblies 2 are installed one by one in the tooling disc assembly 1 in a circumferential arrangement and installation manner, and when the liner assembly 2 and the tooling disc assembly 1 are assembled as a whole, the outer tooth grooves 25 and the inner tooth grooves 26 on the liner assembly 2 are staggered and meshed on the outer tooth disc 13 and the inner tooth disc 14 of the tooling disc assembly 1, which improves the accuracy of the integrated assembly on the one hand, and improves the contact and engagement performance of the liner assembly 2 and the tooling disc assembly 1 on the other hand, so as to avoid the wear-resistant liner from rotating. When the liner assembly 2 is damaged, centrifugal loosening occurs. After the multiple sets of liner assemblies 2 and the tooling disc assemblies 1 are installed one by one, the matching fastening bolts are simultaneously screwed into the positioning screw holes A16 and the positioning screw holes B24, which play a role in screwing and fixing the integrated combination of the liner assembly 2 and the tooling disc assembly 1, so that they form a complete integrated structure. Furthermore, during the assembly and use of the wear-resistant liner, when the liner assembly 2 is damaged, it is only necessary to unscrew the fastening bolts on the corresponding damaged liner assembly 2, and the damaged liner assembly 2 can be repaired and replaced without overall disassembly and assembly, and repair and replacement are simpler and more convenient.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
