Slightly damp material can still work if it does not stick, clump or bridge. Do not use this dry-drum setup for slurry or pulp; use wet magnetic separation instead.<\/p><\/details>\r\n<details><summary>Is higher Gauss always better for a dry drum?<\/summary><p>No. A higher surface field cannot fix a feed layer that is too deep or uneven. It also cannot fix too much distance from the magnet, the wrong drum speed or the wrong splitter position. We select the magnetic system together with the real feed and discharge conditions.<\/p><\/details>\r\n<details><summary>Should I use a dry drum or a magnetic head pulley?<\/summary><p>Use a magnetic head pulley when separation can happen directly at the conveyor head. Use a separate dry drum when you need more control over the feed, magnetic zone, drum speed, splitter and where the two products leave the machine.<\/p><\/details>\r\n<details><summary>Can a standard dry drum separate very fine weakly magnetic material?<\/summary><p>Do not assume it can. For very fine or weakly magnetic targets, we compare a higher-intensity dry separator or another method. If the result is critical, test a sample that matches the real feed in particle size, moisture and target content before finalizing the machine.<\/p><\/details>\r\n<details><summary>How do you select a dry drum for tramp iron removal?<\/summary><p>We start with the iron size, how much iron is normally present, feed width, feed depth, normal and peak feed rate, distance from the magnetic system, impact condition and discharge space. We then set up the machine to capture and continuously discharge the target without creating a new bottleneck.<\/p><\/details>\r\n<details><summary>Can a dry drum magnetic separator be used for magnetite?<\/summary><p>Yes, when the magnetite-bearing material is dry or slightly damp, still flows freely, and the magnetic fraction responds strongly enough to the selected magnetic system. Particle size, feed depth, mineral liberation and whether recovery or product purity matters more should still be checked before final selection.<\/p><\/details>\r\n<details><summary>What proves that a dry magnetic drum separator will work?<\/summary><p>The strongest proof is a test using a sample that matches the real feed and records the feed condition, machine settings and the result that matters for the job. For tramp iron, count captured and remaining targets. For magnetic recovery, weigh the feed and both separated products and use product analysis when required. A surface Gauss number alone does not prove plant separation performance.<\/p><\/details>\r\n<details><summary>What information should I send for selection and quotation?<\/summary><p>Send the material, target contaminant or magnetic fraction, normal and peak feed rate, and the installation condition.
