Technical Field
[0001] The utility model relates to the technical field of boron carbide production, in particular to a meniscus structure of a sand mill for boron carbide production. Background Art
[0002] In the production process of boron carbide powder, the large-particle boron carbide after washing and precipitation must pass through the feed pipe of the sand mill to enter the inside of the sand mill, and the large-particle boron carbide is ground into small pieces by the sand mill. However, in actual applications, due to the high hardness of large-particle boron carbide, the feed pipe of the sand mill will be severely worn during feeding. In addition, the sand mill will also cause wear on the bottom of the feed pipe when it is started, resulting in the feed pipe needing to be frequently shut down for replacement, which not only wastes production time, but also increases the production cost of boron carbide powder.
