Description

Technical Field

[0001] The utility model relates to the technical field of silicon powder production, in particular to a novel device for improving the screening rate of industrial silicon powder. Background Art

[0002] Metal silicon powder refers to the raw materials used in the refractory and powder metallurgy industries. After the metal silicon powder is produced, it needs to be screened to separate the larger particles from the smaller particles. When the existing screening devices are working, many of them are screened manually, and the screening efficiency is low. In addition, the existing screening devices are complex in structure, expensive, large in size, and take up space. For this reason, we propose a screening device for the production of metal silicon powder.

[0003] The existing Chinese patent CN212633354U is a screening device for producing metallic silicon powder. When solving the above-mentioned problem, it can only screen the silicon powder once. When multiple screenings are required, the screened material needs to be poured back into the discharge box for screening. This operation method increases the workload of the staff and is not suitable for popularization. Utility Model Content
