Abstract
Description
Technical Field
[0001] The utility model relates to the field of scrap steel recycling and relates to a scrap steel magnetic separation device. Background Art
[0002] Scrap steel is an important resource in steel production. With the passage of time and the evolution of production models, the proportion of scrap steel in my country's steel raw materials has increased year by year. The source of scrap steel is relatively complex, generally from scrapped cars and white appliances, etc., which are mixed with a large amount of waste plastics, waste rubber and other waste non-ferrous metals. Therefore, they need to be crushed, cleaned and sorted before they can be recycled. Magnetic separators are generally used for sorting scrap steel, but when existing magnetic separators are used for sorting, some plastics and objects that cannot be magnetically attracted are sandwiched between metals that can be magnetically attracted, and the effect of magnetic separation is generally average.

The raw materials are magnetically separated and adsorbed by the electromagnetic roller one. The materials magnetically attracted by the electromagnetic roller one are scraped by the roller scraper plate on the inclined transition plate one and fall down until they enter the middle conveyor belt.
