Magnetic Head Pulley Conversion

High strength extraction of metal contamination

MSA Rare Earth Magnetic Pulley Lagging is the most powerful in the world and on average twice the power of our competitors. MSA apply a proprietary RE80 magnet conversion system to convert your existing head pulleys into high strength magnetic head pulleys. This enables the increase of unwanted tramp iron and metal fragment removal from your product lines without manual labour.

Save money by providing your own pulley for conversion. We also provide complete new magnetic head pulley solutions.

    A BACKGROUND ON PULLEYS

    A conveyor system typically utilizes several different pulley types and sizes that work together to move the belt around. These pulleys can include head (drive) pulleys, tail (return) pulleys, take-up pulleys, and bend pulleys.

     

    Head Pulleys are situated at the discharge terminus of the conveyor. They are responsible for the force that propels the belt around the conveyor. Head Pulleys are usually mounted in external bearings and driven by an external source.

     

    In some applications, such as mining or recycling, it is in the company’s best interest to separate tramp iron and ferrous metal pieces from the underside of the product stream. MSA Magnetic Head Pulleys are a robust, automatic, and efficient solution for moderate belt speeds.

    ADVANTAGES OF MSA MAGNETIC HEAD PULLEYS

    • Improves product purity
    • Continuous, automatic separation of magnetic and non-magnetic material.
    • Prevents damage to expensive downstream machinery such as shredders, crushers, mills, pulverisers, and grinders.
    • Prevents damage to conveyor belts caused by sharp metal pieces – this is especially a risk at discharge points.
    • Reduces downtime, maintenance, and repair costs to damaged downstream equipment and conveyor belts
    • Reduces amount of product sent to landfill
    • Potential savings from avoiding unnecessary landfill
    • Low-cost operation – permanent magnet requires no additional power to operate.
    • Simple installation.
    • High Energy Rare Earth RE80™ Magnets—standard & super high strength deep field options

    PULLEY LAGGING

    MSA can supply complete new Magnetic Head Pulleys or can fit Magnetic Lagging Strips to your existing Pulley.

     

    The addition of Magnetic Lagging Strips to your existing Pulley is not only a cost-effective solution (as opposed to purchasing a complete new Pulley System), but also assists with conveyor belt tracking. The lagging will only cause a small increase in the weight and diameter of the existing pulley.

    HOW MAGNETIC HEAD PULLEYS WORK

    Magnetic Head Pulleys operate much the same as non-magnetic Head Pulleys, except that the metal pieces are discharged separately to the non-magnetic product stream.


    As the product stream reaches the conveyor discharge point, ferrous metal is attracted to the pulleys magnetic field and held to the belt. As the belt moves around the pulley, the non-magnetic material is discharged in a normal trajectory, however, the ferrous metal is still held to the belt. When the belt passes out of the magnetic field, the magnetic material drops off into a separate chute or bin to the rest of the product. A non-magnetic splitter may be installed to separate the two discharges. Ferrous metals commonly extracted from the product stream include nails, nuts, bolts, wire, cans, screws, tools, and so on.
