Eriez Magnetic Head Pulleys are an ideal compact solution for the magnetic treatment of conveyed materials.
Powerful magnets are used to automatically separate tramp iron and fine iron contaminants. These separators can be retro-fitted into existing conveyors or built in during conveyor design.
For maximum ferrous metal recovery, magnetic head pulleys are ideally installed in conjunction with an Eriez Suspended Magnet. This enables maximum recovery of tramp iron throughout the product burden.
Eriez Magnetic Pulleys are widely used as head pulleys in belt conveyors for continuous automatic removal of damaging tramp iron from a variety of materials.
As illustrated in Figure 1, tramp–iron contaminated material comes within the pulley’s magnetic field, the tramp iron is attracted and held to the belt until it reaches the underside, passes out of the magnetic field, and is separately discharged. The cleaned, nonmagnetic material is discharged over the pulley in a normal trajectory.
A stainless steel splitter assembly is required to separate segmented material fractions. An adjustable splitter will permit separation fine tuning and provide optimum separation performance for your application.
