Description

Technical Field

[0002] During the production process of industrial alumina particles, many alumina particle powders with smaller particle sizes are produced. These particle powders need to be screened when producing alumina particles. When using traditional alumina particle powder screening devices, the alumina particle powders are usually placed on a sieve plate, and the sieve plate is used to transmit vibration to the alumina particle powders to achieve alumina particle powder screening. This method can indeed achieve a good screening effect on alumina particle powders, but alumina particle powders are easy to absorb water vapor in the air. Alumina particle powders that come into contact with water vapor are prone to agglomeration, which can easily cause the alumina particle powders to block the sieve holes of the sieve plate. At the same time, the traditional screening device is not provided with a good sieve hole cleaning structure. When the alumina particle powders are screened through the sieve plate, the screening efficiency of the alumina particle powders is reduced. Utility Model Content
