Overhead Electromagnet

Dings Overhead Electromagnets

Overhead Electromagnets are suspended over conveyor belts and vibratory feeders. They are designed to magnetically lift ferrous metals out of bulk material which ensures product purity and protects processing equipment. Any ferrous metal that is attracted to the magnet face is either automatically and continuously removed with our self-cleaning models or held in place on stationary models until the magnet is turned off. Our Overhead Electromagnets remove damaging ferrous tramp metal, which can cause costly repairs and downtime.

20-Year Warranty on Coil Burnout for Overhead Electromagnets

THE BEST WARRANTY IN THE INDUSTRY!

Our electromagnet coils are wound with an anodized aluminum strap; an exclusive design that generates more magnetism than any other electromagnet on the market and exceeds Class “H” insulation rating!  This design outlasts and outperforms “conventional” round wire coils that can lead to coil burnouts.

Dings Electromagnetic Coils

Diagram of Dings Electromagnetic Coil Design

Dings electromagnetic coils are wound with an anodized aluminum strap; an exclusive design that generates more magnetism than any other electromagnet on the market and exceeds Class “H” insulation rating! This design outlasts and out-performs copper wire with polymer insulation or bare aluminum with Nomex® insulation.

Dings electromagnetic coils stay cooler – operating at a much lower temperature. Since electromagnets perform best at lower operating temperatures, this design ensures Dings electromagnets are stronger and more efficient. With “conventional” round wire coils, inside turns are not cooled evenly and product hot spots that damage coils. Each turn of the Dings electromagnetic coil is exposed to oil-cooling and is in constant contact with oil, therefore, eliminating the need for an oil expansion tank. Oil is free to flow around and in between each coil to maximize cooling effect.

  • 20-Year Warranty on coil burnout
  • No insulation needed – eliminating the major cause of coil failure (insulation breakdown)
  • More magnetism and separating power – generated by extra turns
  • Each turn is exposed to oil-cooling (assuring a stronger, more efficient magnet)
  • Eliminates the need for external oil expansion (less pipes or tanks that can easily be damaged)

Self-Cleaning Magnetic Separators

Self Cleaning Overhead Electromagnets

Self-Cleaning Magnetic Separator Models have a belt that continuously travels across the face of the magnet body to automatically discharge attracted ferrous metal away from the magnetic zone. These powerful models come equipped with a heavy-duty rubber belt to remove ferrous metal from the material stream. Other cleat styles and sizes are available for use in different ferrous recovery applications. To drive the magnetic belt, a direct gear motor is used and also available in special voltages.

Dura-belt

A metal clad belt developed by Dings Co. Magnetic Group as a long-life magnet cleaning belt for installations where many sharp-edged iron objects are encountered—especially useful when recycling concrete with rebar. Continuous impacts from sharp steel can cause rapid wear on standard cleaning belts. The entire impact area on a ‘Durabelt’ is protected with an armored barrier of thick stainless-steel pads. The self-cleaning belt travels continuously around the magnetic separator, automatically discharging the attracted ferrous. Individual plates can be easily replaced in the field, saving costs on belt replacement and reducing downtime.

Stationary MAGNETIC SEPARATORS

Stationary Overhead Electromagnet

Stationary Magnetic Separator models are maintenance-free (other than maintaining oil in the electro) with no moving parts (no lubrication, no tightening or replacing of hardware needed). Ferrous metal is pulled out of the material stream to the face of the magnet and held in place until the magnet is turned off. Designed for easy installation; this model comes with a 3-point suspension system that includes two cables and one turnbuckle connected to a common bull ring. Adjustment of the magnet suspension angle is easy and only involves adjustment of the turnbuckle. There is no measuring, shortening, lengthening or cutting of cable required. These magnets are constructed with a stainless-steel bottom wear plate over the impact area.

Inline vs. Crossbelt Mounting Positions

Dings overhead electromagnets are suspended over conveyor belts or vibrator feeders in two configurations: Inline and Crossbelt.

Inline Mounting Position

Inline orientation is a more efficient
mounting position than Crossbelt over the conveyor. With an inline mounted magnet, as the material is discharged from the conveyor it becomes airborne. This liberates the tramp metal making it easier to separate because it doesn’t need to be pulled through the material burden. This along with its lower required suspension height sometimes
permits the use of a smaller more economic magnet in comparison to cross-belt over the conveyor orientation. Inline Magnets are used in conjunction with a splitter to ensure
proper separation between burden material and tramp metal.

Crossbelt Over Conveyor

In a cross-belt over the conveyor belt mounting position the electromagnet is installed at a right angle to the travel direction of the material on the belt. Tramp metal is collected by the magnet and discharged by the magnet’s self-cleaning belt into a collection bin along side the conveyor. This orientation is commonly used when the magnet is being installed in an easily accessible area on an existing conveyor.

Crossbelt Over Head Pulley

Several factors make the cross-belt over the head pulley orientation a more efficient option than mounting over the belt. The first one is the conveyor belt flattens as it reaches the pulley allowing for a reduced suspension height. Secondly, as the material leaves the conveyor it becomes airborne, making it easier to separate because the tramp metal doesn’t need to be pulled through the material burden. These factors also
sometimes permit the use of a smaller more economic magnet. Magnets installed in this position are often used in conjunction with a splitter.
