Overhead Electromagnet

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

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

THE BEST WARRANTY IN THE INDUSTRY!

Dings Electromagnetic Coils

Dings electromagnetic coils are wound with an anodized aluminum strap; an exclusive design that generates more magnetism than any other on the market and exceeds Class “H” insulation rating! This design outlasts and out-performs “conventional” round wire (copper, bare or anodized aluminum) coils that can lead to coil burn-outs.

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 cooing 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 Model

Self Cleaning

Self-Cleaning 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.

Dings Armor-Clad ‘Durabelt’
Special Belt Designs

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. 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 separator, automatically cleaning off the attracted ferrous. Individual plates can be easily replaced in the field, saving costs on belt replacement and reducing downtime

Stationary

Overhead Stationary

Stationary 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 magnets are available in two suspension types: Inline and Crossbelt

In an inline mounting position, the magnet is installed over the conveyor head pulley so that the magnet face is parallel to the travel direction of material falling off the conveyor. The material is loosening up as it travels through its trajectory after leaving the head pulley.

Inline vs. Crossbelt
Inline vs. Crossbelt

In a crossbelt mounting position, the magnet is installed over the conveyor such that the magnet is at a right angle to the travel direction of the material on the conveyor. When compared to an inline mounted magnet, a larger size magnet is required to remove ferrous from a crossbelt application (since ferrous on the belt surface has to be pulled up through the burden). If the magnet cannot be installed over the head pulley, install it over the flat section of the conveyor.
