Description

Technical Field

[0001] The invention relates to the technical field of scrap metal processing, in particular to a scrap metal screening device. Background Art

[0002] Scrap metal recycling refers to the process of collecting, processing and reusing discarded metal materials. Scrap metals include various metal materials such as scrap iron, scrap steel, scrap copper, and scrap aluminum. They can be recycled and reused to reduce resource waste and environmental pollution. Scrap metal recycling helps save energy and reduce environmental pollution, while also creating employment opportunities and economic benefits. After recycling, scrap metals generally need to be crushed, and then they need to be screened, because some scrap metals are not crushed thoroughly enough, resulting in inconsistent particle sizes after the metal is crushed. When metal blocks of different sizes are processed by the eddy current separator, the metal is not finely sorted inside, which affects the sorting effect. Summary of the invention
