How Magnetic Head Pulleys Work
Bunting Head Pulleys have a radial pole design that eliminates dead spots and provides superior retention of ferrous fragments. The radial design is especially effective in holding long, rod-shaped ferrous objects. It rotates them parallel to the pulley face to increase surface contact area for improved holding and separation efficiency.

The sketch below illustrates how Bunting Magnetic Head Pulleys remove tramp metal from contaminated material. As the contaminated material comes into the magnetic field, the tramp metal is attracted and held to the belt until it passes out of the magnetic field. Cleaning is continuous and automatic.

Magnetic Decreasing Force Take-Off Rail Assemblies convey small ferrous contaminants away from the intense magnetic field of the Bunting Magnetic Separation Pulley, eliminating hang-up on the return side of the conveyor belt. The magnetic field is designed to have full magnetic force at the angled end, gradually decreasing down to almost zero at the discharge end for smooth release.

How to Select Magnetic Pulleys
Pulleys typically fit into an existing conveyor system, so several dimensions may already be fixed. Use the belt width column to select a pulley with the correct width for your installation. You may also have to match pulley and shaft diameters to your equipment.
