Description

Technical Field

[0001] This utility model relates to the field of scrap steel recycling technology, specifically to a scrap steel recycling screening device. Background Technology

[0002] Current scrap steel slag recycling equipment on the market suffers from significant structural design deficiencies. It fails to comprehensively and effectively treat the dust within the scrap steel slag, resulting in some dust being recycled along with the slag. This severely impacts the quality of the recycling, causing the recovered scrap steel slag to fall short of ideal purity and quality standards. This can lead to numerous problems in subsequent processing and utilization stages, such as affecting the quality stability of later products, hindering the high-quality development of the scrap steel slag recycling industry. Therefore, it is imperative to optimize the structural design to properly address the critical issue of incomplete dust removal and improve overall recycling quality. Utility Model Content
