This helps you see how much service space the equipment needs. The photo does not tell us the oil type, oil amount, internal flow path, heat-removal rate, or allowable temperature rise. Confirm these items in the technical specification.<\/p>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/section>\r\n<section class=\"cl-section\" id=\"selection\">\r\n<div class=\"cl-wrap\">\r\n<div class=\"eyebrow\">Working Distance and Material Depth<\/div>\r\n<h2>How Do You Set the Working Distance?<\/h2>\r\n<p class=\"lead\"><strong>Measure from the magnet face to the farthest dangerous iron that must be captured.<\/strong> If the iron can be buried at the bottom of the material, include the full material depth. Do not use only the empty space between the magnet and the top of the material.<\/p>\r\n<h3 style=\"margin-top:28px\">Why Does Material Depth Matter?<\/h3>\r\n<p>The deeper the material layer, the farther buried iron is from the magnet. Engineers often call the material layer the <strong>burden<\/strong>, and its depth the <strong>burden depth<\/strong>. If normal production reaches 220 mm even though the average is lower, send us 220 mm. We choose for the hardest normal condition, not the easiest one.<\/p>\r\n<div class=\"grid-3\" style=\"margin-top:20px\">\r\n<div class=\"card\"><h3>Iron Near the Surface<\/h3><p>Use the distance from the magnet face to the target near the top of the material. This is usually the easier capture position.<\/p><\/div>\r\n<div class=\"card\"><h3>Iron at the Bottom<\/h3><p>Add the space above the material and the full material depth. Use this longer distance when bottom iron must be removed.<\/p><\/div>\r\n<div class=\"card\"><h3>Material Depth Changes<\/h3><p>Use the maximum normal material depth.

Oil in the cooling system carries heat away from the electromagnetic coil.<\/p><\/details>\r\n<details><summary>When should I use an oil-cooled suspended electromagnet?<\/summary><p>Use it when you need an energized suspended magnet for conveyor tramp-iron removal, oil cooling is allowed, and the cleaning method matches how often iron appears.<\/p><\/details>\r\n<details><summary>Manual-clean or self-cleaning: which should I choose?<\/summary><p>Choose manual-clean when iron is occasional and the conveyor can stop safely. Choose self-cleaning when iron appears often, captured metal builds up quickly, or production cannot stop for regular cleaning.<\/p><\/details>\r\n<details><summary>Permanent magnet or electromagnet: which should I choose?<\/summary><p>Choose a permanent suspended magnet when it can reach the required iron position without a powered coil. Choose an electromagnet when the target is farther away, buried deeper, or harder to capture than the permanent route can reliably handle.<\/p><\/details>\r\n<details><summary>How do I calculate working distance?<\/summary><p>Measure from the magnet face to the farthest dangerous iron that must be captured. If the iron can be buried at the bottom of the material, include the space above the material plus the full material depth.<\/p><\/details>\r\n<details><summary>Does material depth affect magnet selection?<\/summary><p>Yes. Deeper material places buried iron farther from the magnet. Use the maximum normal material depth when the separator must remove iron from the bottom of the material layer.<\/p><\/details>\r\n<details><summary>Does belt speed affect iron removal?<\/summary><p>Yes. Faster belt speed gives the magnet less time to attract and lift the iron. When speed is high and missed iron can damage important equipment, use a moving-target capture test.<\/p><\/details>\r\n<details><summary>Does higher Gauss mean better conveyor performance?<\/summary><p>No. Gauss is magnetic flux density at a defined point. It does not equal pull force and it does not prove that buried iron will be removed from a moving conveyor.<\/p><\/details>\r\n<details><summary>When do I need a moving-target capture test?<\/summary><p>Use one when missed iron can damage important downstream equipment, the belt is fast, the material is deep, the required target is small or buried, or the project requires a defined capture result.<\/p><\/details>\r\n<details><summary>What information should I send Corvelan?<\/summary><p>Start with belt width, normal and maximum material depth, belt speed, target iron size, approximate weight and shape, installation position, and whether the line can stop for manual cleaning. Add material details, throughput, temperature, drawings, photos, site power and required factory checks when available.<\/p><\/details>\r\n<\/div><\/section>\r\n<section class=\"cl-section\" id=\"selection-data-map\">\r\n<div class=\"cl-wrap\">\r\n<div class=\"eyebrow\">What to Send Us<\/div>\r\n<h2>Tell Us This \u2192 Corvelan Uses It for This<\/h2>\r\n<p class=\"lead\"><strong>Each item answers a real engineering question.<\/strong> Send the real conveyor condition so we can choose the magnet type, cleaning method, installation layout and factory checks.<\/p>\r\n<div class=\"table-scroll\" style=\"margin-top:24px\"><table class=\"choice-table\">\r\n<thead><tr><th>You Send<\/th><th>Corvelan Uses It For<\/th><th>If It Is Missing<\/th><\/tr><\/thead>\r\n<tbody>\r\n<tr><td>Belt width<\/td><td>Magnet coverage and installation width.<\/td><td>We cannot confirm coverage.<\/td><\/tr>\r\n<tr><td>Normal and maximum material depth<\/td><td>Deepest target position and working distance.<\/td><td>We cannot confirm the hardest target position.<\/td><\/tr>\r\n<tr><td>Belt speed<\/td><td>Available capture time and whether a moving-target test is needed.<\/td><td>A stationary check may not represent production.<\/td><\/tr>\r\n<tr><td>Target iron size, weight and shape<\/td><td>The iron piece that matters most for the job and the factory test.<\/td><td>\u201cRemove iron\u201d is too vague for a useful test.<\/td><\/tr>\r\n<tr><td>Where the iron can sit in the material<\/td><td>Surface, middle or bottom test position.<\/td><td>The test can become easier than the real job.<\/td><\/tr>\r\n<tr><td>How often iron appears<\/td><td>Manual-clean or self-cleaning.<\/td><td>The wrong cleaning method can create unnecessary stops.<\/td><\/tr>\r\n<tr><td>Conveyor drawing or photos<\/td><td>Crossbelt, inline or mid-belt layout, support, nearby steel, discharge route and service access.<\/td><td>Installation details remain open.<\/td><\/tr>\r\n<tr><td>Site temperature and power supply<\/td><td>Electrical and cooling setup.<\/td><td>These items cannot be confirmed.<\/td><\/tr>\r\n<tr><td>Required factory checks<\/td><td>What must be measured or tested before shipment.<\/td><td>PASS\/FAIL can become unclear after production starts.<\/td><\/tr>\r\n<\/tbody><\/table><\/div>\r\n<\/div>\r\n<\/section>\r\n<section class=\"cl-section rfq\" id=\"rfq\">\r\n<div class=\"cl-wrap rfq-grid\">\r\n<div>\r\n<div class=\"eyebrow\" style=\"color:#a9d5f5\">What to Send Us<\/div>\r\n<h2>Send These 6 Items First<\/h2>\r\n<p class=\"lead\">Send us these six items first.
