Abstract
Description
Technical Field
[0001] This utility model relates to the field of alumina screening technology, specifically to a multi-layer screening device for alumina powder. Background Technology
[0002] Alumina is an important industrial raw material. During the production process, the particle size, distribution, and purity of alumina powder directly affect the subsequent production efficiency and product quality.

They often fail to meet the high requirements of modern industry for production efficiency and product quality. Screens with a single mesh size are difficult to separate different particle sizes, which can easily cause screen blockage and reduce work efficiency. Utility Model Content
