[0004] BACKGROUND

[0005] A ball mill is a powder or slurry grinding and dispersing device, which is widely used in the fields of electronics, chemical industry and materials. Both scientific research experiments, industrial trial production, and ball mills play a crucial role. The milling and dispersion of the ball mill, which is actually a mechanochemical process, can achieve improvements in the size and other characteristics of the material by high speed collisions and friction between the milling media and the material. The high-speed high-energy ball mill has a wide application in the field of new materials by increasing the rotation speed to more than 1000 revolutions per minute, thereby improving the ball milling energy and achieving the effect of chemical alloys. The planetary ball mill in the current market generally adopts a gear structure, and the gear transmission has the advantages of simple and reliable structure, and the traditional structure has many disadvantages mainly in the following aspects: (1 ) gear transmission inevitably has mechanical wear, high mechanical processing requirements, and good daily lubrication and maintenance; (2) the gear adopts a steel structure, generally, the ball mill is heavy, and the operation energy consumption is high; (3) gear transmission is adopted, the transmission ratio is fixed, the speed ratio of the large wheel and the planet gear is not changed, and the sample processing capacity is limited; and (4) the gear transmission limits the rotating speed, the maximum speed of the ball mill is about 350 rpm, the planetary gear is 700 rpm, and the speed ratio is 2: 1 The above defects limit the use of the planetary ball mill, especially the research and development and production processes of some special new materials, cannot meet the development of the current new material field, and are difficult to meet the requirements of modern scientific experiments and high-technology product production.
