[0002] Cubic boron nitride is synthesized from hexagonal boron nitride and catalyst under high temperature and high pressure. It is a new type of product that appeared after the advent of artificial diamond. In the production process of cubic boron nitride, it is necessary to mix a variety of raw materials to ensure the production quality of cubic boron nitride.

[0003] In the prior art, in order to ensure the uniformity of mixing, different raw materials are usually added and stirred one by one, which effectively avoids the problem of incomplete mixing caused by raw material accumulation. However, in this way, the machine needs to be stopped when adding materials. At the same time, multiple additions will also increase the workload of the staff and reduce the overall mixing efficiency to a certain extent. There are certain shortcomings. In view of this, we propose a multi-raw material mixing device for the production of cubic boron nitride. Utility Model Content
