width, coal load depth, belt speed, tramp iron condition and installation space. Equipment selection should be based on your actual conveyor system, not only magnet strength.<\/p>\r\n<p class=\"hero-copy\">Corvelan helps coal plants select suspended magnets, self-cleaning overband magnets, magnetic head pulleys and magnetic drums based on where metal contamination occurs and what equipment needs protection. If the target is pyrite rather than tramp steel, representative coal testing is recommended before equipment selection.<\/p>\r\n<a class=\"cta\" href=\"https:\/\/www.corvelanmag.com\/contact-us\/\">Request Coal Conveyor Evaluation<\/a>\r\n<div class=\"quick\"><strong>Quick answer:<\/strong> use suspended or self-cleaning overband magnets as the main recommended solution for ferrous tramp above coal conveyors; consider a magnetic head pulley when separation belongs at the conveyor discharge; use a magnetic drum when coal can be presented as a controlled dry stream.

The final choice depends on coal layer depth, belt speed, tramp iron, working distance, cleaning requirement and available iron discharge space.<\/p><\/details>\r\n<details><summary>When should I use a self-cleaning overband magnet?<\/summary><p>Use a self-cleaning option when captured-metal loading or production continuity makes repeated manual cleaning impractical and there is enough space to discharge the captured iron safely.<\/p><\/details>\r\n<details><summary>Inline or crossbelt: which installation is better?<\/summary><p>Neither is universally better. Inline installation can benefit from head-end material geometry, while crossbelt installation offers side discharge and flexible placement. The decision depends on coal layer depth, headroom, conveyor geometry and reject clearance.<\/p><\/details>\r\n<details><summary>How does coal layer depth affect tramp iron removal?<\/summary><p>Coal layer depth changes the distance between the magnetic source and iron buried inside the coal bed. A deeper burden can make the most difficult target much farther from the magnet than a surface measurement suggests.<\/p><\/details>\r\n<details><summary>Is higher Gauss always better for coal iron removal?<\/summary><p>No. Gauss must be tied to a measurement position. Working distance, field gradient, target size and shape, belt speed and feed presentation all influence whether the contaminant is actually captured and removed.<\/p><\/details>\r\n<details><summary>Can magnetic separation remove pyrite from coal?<\/summary><p>Potentially, but it should be treated as a test-driven mineral separation problem. Liberation, particle size, mineralogy, magnetic response and analytical acceptance criteria must be evaluated on representative coal. Magnetic separation does not remove organic sulfur.<\/p><\/details>\r\n<details><summary>What information does Corvelan need before recommending a coal magnetic separator?<\/summary><p>Send coal type, particle size, throughput, moisture, target contaminant, conveyor or chute width, belt speed, coal layer depth, installation photos or drawings, and the required separation result.
