Description

Technical Field

[0001] The invention belongs to the field of diamond processing, and in particular relates to a diamond material mixing device. Background Art

[0002] In previous technologies, diamond mixing equipment mainly uses simple stirring or tumbling methods for mixing. These traditional methods have many limitations. Specifically, first of all, the uniformity of diamond mixing is difficult to ensure. Due to the differences in size, shape and density of diamond particles, traditional equipment is difficult to achieve uniform distribution of each component at the microscopic level, resulting in unstable product performance. Secondly, it is easy to cause damage to diamond material particles. Strong stirring or collision may cause material particles to break, wear and tear on the edges and corners, thereby affecting their quality and use effect. Furthermore, the mixing efficiency is low, and the long mixing process consumes a lot of time and energy, which cannot meet the needs of modern industrial efficient production. Finally, the degree of automation of the mixing is low, the operation process relies on manual experience, and it is difficult to accurately control the mixing parameters, resulting in poor consistency in product quality.

[0003] With the rapid development of science and technology, higher requirements are put forward for diamond mixing equipment. The application of advanced sensor technology, automatic control theory and new materials has provided the possibility to solve the problems of traditional mixing equipment.
