Head Pulley Magnet

Head Pulley Magnet

Head pulley magnet is one of the simplest, yet most effective, magnetic separators. Just mount it in place of a standard head pulley and it easily and efficiently separates ferrous metal from the product stream.

A Dings DFC head pulley magnet is built using our exclusive flux control magnetic circuit. This design ensures continuous magnetism around the entire circumference of the head pulley – no dead spots. For less critical applications, a conventional magnetic circuit design is also offered.

A Dings head pulley magnet is designed to provide years of trouble-free service:

• Permanent magnet means no energy consumption
• Uniform magnetic field
• Large selection of widths and diameters available
• Crowned face for conveyor belt tracking
• Weatherproof stainless steel face
• Shipped ready to install
• Optional lagging available

Perma Pulleys are permanent magnetic separators that operate as head pulleys on belt conveyors. These self-cleaning magnets remove tramp iron and purify material conveyed in bulk form. In many applications, it’s possible to replace an existing head pulley with a Perma Pulley, on a size-for-size basis. A wide range of diameters, widths, and shaft sizes are available.

Head Pulley Magnet

Reasons for using a head pulley magnet:

• Cost effective separation for material depths up to 8-1/2″
• No operating costs
• Excellent for secondary separation after an overhead or drum magnet
• Excellent for tramp iron protection for cushers, grinders, pulverizers, screens and other processing equipment
• Increases product purity in food, chemicals, plastics, glass by removing unwanted iron

Options available:

• Lagging for belt traction
• Center crown strip for belt tracking
• Paint to match current equipment
