Introduction
In industries ranging from recycling to quarrying, overband magnets play a crucial role in removing ferrous metals from materials on conveyor belts. Selecting the right overband magnet ensures product purity, protects machinery, and enhances operational efficiency. In this guide, we’ll break down everything you need to know—from types and applications to selection tips—so your team can make informed decisions.
What is an Overband Magnet?
An overband magnet, also called a conveyor belt magnet, is a type of magnetic separator installed above conveyor belts. When sourcing these devices, it is important to work with a reliable magnetic materials supplier like Souwest Magnetech. Its core function is to attract and remove tramp iron such as nails, bolts, or scrap pieces, preventing equipment damage and material contamination.
