Eriez Suspended Permanent Magnets Offer Cost-Saving Benefits
BY AsphaltPro Staff

The CP-20 and TP-25 suspended permanent magnets from Eriez®, Erie, Pennsylvania, offer cost-saving benefits to operators when installed upstream of crushers, shredders, grinders and other size-reduction equipment, according to the manufacturer. According to Eriez experts, tracking studies and customer testimonials, the expense of one of these high-powered permanent magnets is justified when considering that the magnet’s price point is significantly less than the cost of downtime and repairs associated with damage to essential equipment. The suspended magnetic separators have proven most effective for the removal of unwanted iron from heavy burdens of bulk materials being transferred on conveyor belts. The tramp iron removal provided by these Eriez magnets safeguards costly processing machinery and assures the purity of the product.
Chris Ramsdell, Eriez separation product manager, reported that demand for the CP/TP suspended magnets is expanding in correlation with the growing trend for mobile systems, such as mobile recycling plants and mobile aggregate processing plants. These magnets offer a permanent magnetic field combined with a small installation footprint, making them ideal for mobile systems. The self-cleaning magnets offer hydraulic drives for installation locations where power is not readily available.
The SP-20 series magnets provide a magnetic field across the feed belt to remove damaging tramp iron while the TP-25 series magnets use a twin pole magnetic circuit to provide maximum ferrous removal at higher suspension heights.
Eriez now offers CP-20 and TP-25 suspended permanent magnets as part of its quick ship program. Models in the line are available in both self-cleaning and manual cleaning designs. Manual clean magnets include a drawer type stripper plate and cable sling suspension.
