Overband magnetic separators are devices used to remove ferrous materials from non-magnetic materials on conveyor belts. They consist of a magnet suspended above the conveyor, which attracts and pulls out metal contaminants, ensuring product purity and protecting machinery from damage. These separators are commonly used in industries such as recycling, mining, and food processing. By efficiently separating unwanted metal, overband magnetic separators help improve product quality and operational efficiency, making them essential in various manufacturing and processing applications.
