Description

Technical Field

[0001] The utility model relates to the technical field of metal matrix composite material processing, in particular to a mixing device for producing metal matrix composite materials. Background Art

[0002] Metal matrix composites are composite materials made of metals and their alloys as the matrix and one or more metal or non-metal reinforcement phases. Most of the reinforcement materials are inorganic non-metals, such as SiC, Al2O3, TiB2 and other ceramic phases and carbon phases such as carbon nanotubes and graphene. They are characterized by high specific strength, specific stiffness, low thermal expansion and good friction and wear effects.

[0003] In the production of metal matrix composite materials, a ball mill mixing device is required to mix the raw materials of metal matrix composite materials. When the ball mill cylinder rotates, the grinding body attached to the liner of the ball mill cylinder rotates with the ball mill cylinder due to inertia, centrifugal force and friction. When it is brought to a certain height, it is thrown down due to its own gravity. The falling grinding body crushes the materials in the ball mill cylinder like a projectile, and there is a collision between the ball mill cylinder and the liner of the ball mill, which is easy to be damaged. The patent with the search application number CN202222316076.8 proposes a metal powder ball mill, wherein the liner and the ball mill are of the same cylindrical shape, the liner is placed in the ball mill, and the liner is fixedly connected to the ball mill. During the use of the metal powder ball mill, the internal grinding body constantly collides with the liner, which can easily damage the liner. The metal powder ball mill proposed in the above patent has a liner fixedly connected to the ball mill. After the liner is damaged, it is not convenient to replace the internal liner, which affects the subsequent ball milling effect of the metal-based composite material. Therefore, a mixing device for the production of metal-based composite materials is proposed to solve the problem that the damaged liner of the ball mill is difficult to replace.
