A surface Gauss or mT value alone cannot predict separation performance.<\/p>\r\n<div class=\"cl-grid-2\">\r\n<article class=\"cl-card cl-top\"><h3>What Is the Working Distance?<\/h3><p><strong>Working distance is the real distance from the magnet face to the iron you need to remove.<\/strong> It includes the air gap above the material plus the depth of the target inside the material layer. If the target is buried deeper, the magnet must reach farther. This is why material depth can change the model even when belt width stays the same.<\/p><\/article>\r\n<article class=\"cl-card\"><h3>Does a Higher Gauss Number Mean Better Separation?<\/h3><p><strong>No.<\/strong> Gauss and mT describe magnetic flux density at a defined measurement point.

It does not mean the multi-disc mineral-processing separator used for weakly magnetic mineral beneficiation.<\/p><\/details><details><summary>When should I choose the manual-clean RCDB disc type?<\/summary><p>Choose the manual-clean RCDB when the material is dry and moves on a conveyor. The target should be iron or steel that a magnet can attract. This option fits best when tramp iron appears only from time to time and the line can stop for cleaning. If iron appears often or the line cannot stop, choose a self-cleaning suspended separator instead.<\/p><\/details><details><summary>When should I choose a self-cleaning separator?<\/summary><p>Choose a self-cleaning suspended or cross-belt electromagnetic separator when tramp iron is frequent, automatic discharge is required or repeated manual-cleaning stops would interfere with production.<\/p><\/details><details><summary>Can I select the separator only from throughput?<\/summary><p>No. The same throughput can create different material depths depending on belt width, belt speed, bulk density and feed distribution. Use throughput together with belt width, actual belt speed, normal and maximum material depth and the target iron.<\/p><\/details><details><summary>Which RCDB model fits a 1,000 mm conveyor?<\/summary><p>Start with RCDB-10 because it is the documented family reference for a 1,000 mm belt. Keep RCDB-10 only after checking the real distance from the magnet to the iron, normal and maximum material depth, belt speed, target iron and installation. If those conditions do not fit, change the model or choose another separator.<\/p><\/details><details><summary>How high should the electromagnet hang above the conveyor?<\/summary><p>Do not use one hanging height for every job. Send the magnet-face-to-belt distance plus normal and maximum material depth. We check the real distance to the hardest iron target, because iron buried near the belt is farther from the magnet than iron near the top of the material.<\/p><\/details><details><summary>Does \u201ccontinuous\u201d in the family table mean automatic iron discharge?<\/summary><p>No. \u201cContinuous\u201d is the operating-mode wording in the source family data. It does not mean the manual-clean RCDB automatically removes captured iron. If you need automatic discharge, choose a self-cleaning suspended separator.<\/p><\/details><details><summary>Does a higher Gauss or mT value guarantee better iron removal?<\/summary><p>No. Gauss and millitesla describe magnetic flux density at a defined measurement point. They are not pull force and they are not separation efficiency. Capture also depends on working distance, target size and shape, material depth, belt speed and material condition.<\/p><\/details><details><summary>Do I need a separate electrical control cabinet?<\/summary><p>Some photographed Corvelan configurations use a separate control cabinet. Tell us the site voltage and frequency, whether you need local or remote control, any PLC interlock or I\/O signals, and the installation environment. We use those details to define the electrical arrangement for the quotation.<\/p><\/details><details><summary>How should the final separator be checked?<\/summary><p>If you need a magnetic-field value, measure it at a stated point. If you need confirmation that a critical iron piece can be removed, run that piece or a representative piece through the conveyor. If you need to confirm the installed unit, use a functional check. If you need a removal percentage, agree a full performance test before the test starts; do not use surface Gauss as the acceptance result.<\/p><\/details><details><summary>What should I send Corvelan for selection and quotation?<\/summary><p>Send the material, target iron, throughput or conveyor loading, belt width, belt speed, normal and maximum material depth, magnet-face-to-belt distance, available headroom, site power and a photo or drawing of the proposed installation point. Add acceptance criteria, hazardous-area classification or plant control requirements when they apply.<\/p><\/details><details><summary>What does Corvelan check before confirming a separator?<\/summary><p>We use different information for different questions. Product photos confirm the physical product. The RCDB family table gives a starting model. The selected-model drawing confirms installation details. A magnetic measurement shows only the stated field value. Use an agreed iron-piece test when the order needs to confirm that a defined iron piece can be captured under the stated condition.<\/p><\/details><details><summary>Are the A\/B\/C\/D examples on this page real customer projects?<\/summary><p>No. They are selection examples created to show how the choice changes when the process changes.
