point’ drop in magnetic force and no decline in performance due to heat rise. “Prior to the introduction of P-REX, processors have had to accept reduced revenue because of more limited metal recovery systems — but no longer,” says Mr. Shuttleworth. With today’s electromagnetic drum magnets, a steel core is used to project the magnetic field. These cores generate a limited magnetic force at the drum edge because the electric coil that is wound around the core takes valuable space across the width of the drum, resulting in weak zones at the edges. These weak zones can amount to 20 percent or more of the surface of the drum. Because the P-REX is a permanent magnet, it extends to the edge of the drum. That means wider and more efficient separation. Wider separation means greater profits through greater recovery. Today’s design of electro-axial drums have a significant reduction in magnetic strength at the transfer point, or “flip” point, along the arc of the ferrous material’s travel, resulting in lost recovery. Not with the patent-pending P-REX. The ferrous material is powerfully transferred and flipped from magnetic pole to magnetic pole to magnetic pole, resulting in a cleaner product and more recovery. Electro Drums consume power and heat up much like a light bulb does during use. The higher the heat, the greater is the loss in strength. Shuttleworth explains, “Check the gauss strength of your drum at the end of the shift and you will see that the electro drum has lost up to 30 percent of its strength.” He adds, “In the summer and in southern climates, this can be an even greater issue.” P-REX’s permanent magnets are permanent; they maintain their strength. P-REX lasts forever and uses no electricity. It is very strong with an attractive force that surpasses the largest and strongest electro drums on the market today. When comparing P-REX Drums to Electros, P-REX outperforms them by more than 20 percent during both hot and cold conditions. When drum magnets don’t operate at peak performance, large sphere-shaped meatballs and knuckles become impossible to capture. Fragments of electric motors and alternators and other items containing copper, aluminum and steel are missed, money is lost and dangerous fluff fires often result.
