Recovered metal objects are removed automatically from the magnetic zone. These powerful separators come equipped with a heavy duty rubber belt with 1” vulcanized cleats to continuously remove metal from the product stream (3” cleats available for material recycling facilities).

Just suspend it over the conveyor or over the head pulley. When the magnet surface starts to fill up, swing the magnet away from the conveyor and cut the power to release the at-tracted metal. Then swing the magnet back over the conveyor or head pulley. Each Dings stationary overhead magnet is constructed with continuously welded stainless steel bottom plate, steel side plates and backplate. With no moving parts, there is nothing to lubricate, tighten or replace. You’ll also find it easy to install your Dings magnet. It comes complete with a conve-nient 3 point suspension system consisting of two cables and one turnbuckle connected to a common bull ring. To change the suspension angle, simply adjust the turnbuckle. There’s no measuring, shortening, lengthening or cutting of cable. Options• Hazardous location models available• CSA approved models available• Suspension systems - turnbuckles, trolleys, wire ropeFeatures• 10-Year warranty against coil burnout• No need for external expansion tank - oil expansion takes place internally• Coil exceeds Class “H” insulation rating• Stainless steel bottom plate, steel side plates and backplate• Easy installation• Additional wear plate provides extra protection for the magnet impact areaStationarySevere Duty Additional Features• Armor-clad Durabelt• Heavy duty drive package• Lagging on the drive pulley• Individual plates or cleats can be easily replaced in the field, saving on belt replacement costs and reducing downtime This rugged version of the overhead magnet is designed for severe-duty applications such as concrete recycling and construction and demolition debris. The armor-clad Durabelt prolongs belt life in applications with sharp-edged steel or with frequent impact from large quantities of ferrous. Full-width metal cladding is available as an option for crossbelt applications. Severe DutyOverhead separators suspend above belt or vibratory conveyors, magnetically lifting ferrous metals out of bulk material. They are used for steel recovery, separating ferrous metals from nonmagnetic material. Overhead magnets also protect processing equipment, removing damaging tramp metal that can cause costly repairs and downtime. 10-YEAR WARRANTYAgainst Coil BurnoutOther features:• Easy access to oil level, drain, and fill plugs• Common size pulleys and pillow block bearings• Four lifting lugs• One way pressure relief valve keeps moisture out• NEMA 4 weather-tight magnet box and terminal connection box• Full 7-gauge stainless steel bottom plate with extra replaceable center wear plate at area of impact• Stainless steel crossbelt deflector reduces wear, minimizes cleaning & extends belt life; Interchangeable side to side INDUSTRY’S BEST 10-YEAR WARRANTYExclusive Coil Design Protects Against Magnet Burn-outFeaturesDings electromagnets are wound with anodized aluminum strap, an exclusive design that lasts longer and generates more magnetism than any other on the market. • Coils don’t require additional insulation• Extra turns fit into same area- generating more magnetism and power• Every turn exposed to oil cooling - cooler coils perform better• Eliminates the need for external oil expansion tankHeavy duty beltwith 1” cleats standardMRF belt, severe duty belts availableOption of electric or hydraulic motorHeavy Duty frame construction IP56 AGMA class II direct gear motorOperation in temperature -25° C to 60° C Stainless steel crossbelt deflector End crown curved pulley for belt trackingBreather valveOil level plugDrain plugNEMA 4 weather-tight terminal connection boxFill plugSizesSelf-Cleaning ModelsStationary ModelsMagnet ModelWeight (lbs)Power (watts)A LengthB WidthC Suspension HeightD Box Height221,700 2,84836" 30" 46" 18"22T 30" 36" 46" 18"332,450 4,53042" 36" 48" 18"33T 36" 42" 48" 18"443,600 6,48348" 42" 57" 19"44T 42" 48" 57" 19"555,200 8,06454" 48" 64" 22"55T 48" 54" 64" 22"667,100 9,47560" 54" 68" 23"66T 54" 60" 68" 23"779,950 12,24566" 60" 90" 27"77T 60" 66" 90" 27"8810,750 14,17972" 66" 91" 28"88T 66" 72" 91" 28"9916,200 14,72578" 72" 90" 29"99T 72" 78" 90" 29"Magnet ModelWeight (lbs.)Power (watts)Drive Motor (h.p.)A LengthB WidthC OverallD Overall E HeightF BeltG FrameInline Crossbelt Inline Crossbelt Inline Crossbelt Inline Crossbelt Inline Crossbelt Inline Crossbelt222,600 2,848 536" 30" 30" 36" 78" 72" 49" 55" 18" 24" 30" 37" 43"22T 30" 36" 36" 30" 72" 78" 55" 49" 18" 30" 24" 43" 37"333,450 4,530 542" 36" 36" 42" 84" 78" 55" 61" 18" 30" 36" 43" 49"33T 36" 42" 42" 36" 78" 84" 61" 55" 18" 36" 30" 49" 43"444,700 6,483 548" 42" 42" 48" 90" 84" 61" 67" 19" 36" 42" 49" 55"44T 42" 48" 48" 42" 84" 90" 67" 61" 19" 42" 36" 55" 49"556,400 8,064 554" 48" 48" 54" 96" 90" 67" 73" 22" 42" 50" 55" 61"55T 48" 54" 54" 48" 90" 96" 73" 67" 22" 50" 42" 61" 55"669,000 9,975 560" 54" 54" 60" 113" 107" 73" 79" 23" 48" 54" 61" 67"66T 54" 60" 60" 54" 107" 113" 79" 73" 23" 54" 48" 67" 61"7712,500 12,245 566" 60" 60" 66" 119" 113" 79" 85" 28" 54" 60" 67" 73"77T 60" 66" 66" 60" 113" 119" 85" 79" 28" 60" 54" 73" 67"8815,650 14,179 7.572" 66" 66" 72" 128" 122" 89" 95" 28" 60" 66" 75" 81"88T 66" 72" 72" 66" 122" 128" 95" 89" 28" 66" 60" 81" 75"9918,400 14,725 7.578" 72" 72" 78" 134" 128" 95" 101" 29" 66" 72" 81" 87"99T 72" 78" 78" 72" 128" 134" 101" 95" 29" 72" 66" 87" 81"Non-magnetic areaMagnetic performance is affected by magnetic material in the field; in the shaded area, no construction parts that can be magnetized are permitted. Pulleys, rollers, frames, supports, etc., must be made of material that cannot be magnetized. When installing the magnet in-line, the head pulley must be non-magnetic.Model Suspension HeightWidth “A”Length “B”22 UP TO 10” 30” 36”33 UP TO 13” 36” 42”44 UP TO 15” 42” 48”55 UP TO 17” 48” 54”66 UP TO 19” 54” 60”77 UP TO 21” 60” 66”88 UP TO 24” 66” 72”99 UP TO 27” 72” 78” 1/3 “A”1/3 “A”2/3 “A”Magnet width“A”1/3 “A”1/3 “A”2/3 “A”Magnet length “B” 1/3 “A”1/3 “A”2/3 “A”Magnet length “B”CrossbeltCrossbeltIn-lineNon-magnetic areashown as shaded areasAC RectifiersAll electromagnets require a steady DC current. Dings rectifiers are designed to transform the alternating current from your local power source to the necessary direct current. FEATURES • DC wattage up to 50Kw to match separator requirements• No maintenance solid state silicon diode• Voltage regulation within 3.5% from no load to full load• Overload capacity for short infrequent periods• Hinged door cabinet for easy access• Available in NEMA 12, 4, 4XSS, or 9• Delta-Wye constructionA Self-Cleaning electro overhead magnet is available in two suspension types: Inline and Crossbelt. An Inline magnet is installed over a conveyor head pulley so that the cleaning belt runs parallel to the travel direction of material falling off the conveyor. The head pulley must be made from non-magnetic material. A Crossbelt magnet is installed over a conveyor so that the cleaning belt runs at a right angle to the travel direction of the material on the conveyor. Magnetic performance may be affected by magnetic material in the field. This includes such items as I-beams, metal supports, hoppers, or splitters. These and other ferrous objects need to be kept out of the magnetic zone. Magnetic performance may be affected by magnetic material in the field: see “Non-magnetic area” on the next page.Suspension height is critical to the performance of the magnet. This distance is measured from the bottom of the magnet face to the surface of the material handling belt. Elevate the magnet to the suspension height that is appropriate for the application. An appropriate height is 2” – 3” above the top of the conveyed material or the height specified at the time of purchase. If a height is specified, measure it at the middle of the conveyor belt, on its surface, up to the magnet face – the bottom surface of the magnet.If the magnet is too high above the burden, sufficient magnetism may not reach into the burden and cause a loss in separation efficiency. For best results, crossbelt separators should be centered over the belt and paral-lel to the slope of the belt conveyor. InstallationStationaryCrossbelt In-lineIMPORTANT:IN-LINE installation is preferred because separation efficiency is better when the magnet is located over where the conveyed material opens up during its path through the air.
