Magnetic Pulleys

Eriez Magnetic Pulleys

Eriez provides a uniform permanent magnetic pulley that will transform your belt conveyor into a powerful self cleaning magnetic separator. The axial interpole magnetic circuit provides a uniform magnetic field to remove tramp iron from material on almost any belt conveyor.

Eriez Magnetic Pulleys provide ideal automatic removal of unwanted iron from materials conveyed on belts to prevent machinery damage and product contamination for sand, gravel, limestone, recyclables, wood products, food, chemical, mining, rock products, ceramic, paper, plastic, rubber, coal handling and foundry operations.

Features & Benefits:

• Powerful and reliable
• Prevents machinery damage and product contamination
• Automatic separation of heavy tramp iron from conveyor transported materials

Principle of Operation

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.
