[0025] In order to increase the weight of the grinding ball body 100 through the counterweight assembly, obtain a greater impact when flipping and grinding, and effectively grind, in the present embodiment, preferably, the counterweight assembly includes a mounting groove 1021 opened at the middle position inside the sphere 101 and the sphere 2 102, and the inside of the two mounting grooves 1021 is closed with a counterweight ball 1022, so that the counterweight ball 1022 can be conveniently installed inside the mounting groove 1021.

[0030] The working principle and use process of the utility model: before use, the regular dodecahedron grinding ball of the ball mill can be cast into shape by a casting mold to form the sphere 101 and the sphere 2 102. After the sphere 101 and the sphere 2 102 are closed, a regular dodecahedron sphere structure is formed. Therefore, the casting mold inclined surface structure of the outer surface of the sphere 101 and the sphere 2 102 is larger, which is more conducive to demoulding after casting.

[0031] Then, after the grinding ball body 100 is molded, the outer thread mounting ring 1025 is closed on the outer surface of the threaded rod 4 1027 on the surface of the clamping ball 1024. After the threaded rod 4 1027 is rotated to the inside of the internal thread hole 1026, the clamping ball 1024 is closed inside the internal thread groove 1023, and the outer thread mounting ring 1025 is rotated and installed at the end of the internal thread groove 1023 to reinforce the clamping ball 1024, so that the threaded rod 4 1027 is rotated and fixed, and the ball 2 102 is fixed with the ball 1 101 and the counterweight ball 1022. The counterweight ball 1022 is fixed inside the ball 101 and the ball 2 102 for counterweight operation, and after the ball 101 and the ball 2 102 are installed, a regular dodecahedron spherical structure is formed on their outer surfaces. When the grinding ball body 100 is turned over and ground inside the ball mill, the regular dodecahedron spherical structure and the grinding ball body 100 are turned over under the counterweight to obtain a greater impact, which enhances the grinding effect on the object to be ground, and is not easy to cause flattening and breaking of the ball, thereby improving the grinding effect of the grinding ball body 100 placed inside the ball mill;

[0032] Finally, after the sphere 101 and the sphere 2 102 are counterweighted and installed, the sphere 2 102 is closed on the surface of the sphere 101, and the threaded rod 3 1012 is passed through the inside of the through hole 1011, and the nut 1013 is rotated and installed at the end of the threaded rod 3 1012 to fix it. After the fixation, the reinforcement nut 1014 is rotated to strengthen the fixation, so that the sphere 101 and the sphere 2 102 are counterweighted and closed and installed to strengthen the fixation for use, thereby improving the fixation of the grinding ball body 100 when it is frequently turned over and ground inside the ball mill, and it is not easy to loosen. Similarly, when the sphere 101 or the sphere 2 102 is damaged after long-term use, it is easy to replace them separately, and it is convenient to disassemble and replace, and partial replacement reduces the replacement cost.
