Description

Fine powder mixing device

Technical Field

The utility model relates to the technical field of material mixing devices, in particular to a fine powder material mixing device.

Background

The white corundum fine powder has the characteristics of high purity, high temperature resistance, good heat stability, acid and alkali resistance and the like, and is widely applied to daily life ceramics such as abrasive materials, grinding and polishing materials, refractory materials, precision casting materials, steel refractory materials, chemical refractory materials, electroceramics, decorative ceramics and the like, and high-tech industries such as military, electronics and the like. Because the application is wide, the granularity requirements of various industries on white corundum fine powder are greatly different, especially the mixed fine powder with the granularity of 0.09 mm-1.1 mm is required to be uniformly mixed, and analysis cannot be formed because of the large granularity difference (namely, the large granularity is clustered together and the small granularity is clustered together). When the product is prepared, mechanical stirring and wind mixing cannot be used, and secondary crushing of granularity can be caused by stirring and wind mixing, so that the quality of the product is affected. At present, repeated mixing is carried out manually, and the production efficiency is low.
