Magnetic Separation Head Pulleys
Our comprehensive line of powerful permanent Magnetic Separation Pulleys are typically installed as magnetic head pulleys and occasionally as magnetic tail pulleys in conveyor system applications to improve product purity and protect equipment from metal damage. They provide effective, automatic and continuous removal of tramp metal from a material flow.
As the belt conveyed product travels over the magnetic head pulley, any ferrous metal that is mixed in with the product is attracted and held to the face of the belt and carried to the underside of the pulley. After the metal passes out of the magnetic field, it is released and discharges into a chute or bin for analysis or disposal.
Commonly used in industries such as waste recovery, feed and grain and mining, IMI Magnetic Pulleys are available in a wide variety of strengths and standard sizes to fit most belt configurations.
Javelin™ HG Separation Pulley Magnets
The Javelin™ HG separation pulley magnet is a designed to attract and hold low grade, weakly magnetic, stainless steel scrap found in electronic scrap, wire chopping lines and auto shredder residue.
300 grade stainless steel in its pure form has virtually no magnetic potential, however after it has been cold worked or shredded, the potential increases to the point where it can be held by a very strong magnet. Many of the other grades of stainless in their natural state do have magnetic potential so they too are susceptible to magnetic attraction.
This product practically eliminates the need for manual picking of small stainless pieces out of the waste stream. Especially in the wire chopping lines, where the introduction of stainless into the feed stream to the final granulators wreak havoc on granulator blades and grates.
These units are available an all in one conveyor unit or should as stand alone head pulleys that can be integrated into existing conveyor systems. It is recommended the unit is fed with a vibratory feeder in order to give the material the best spread across the belt and eliminate clumps which reduce performance.Literature Download: Magnetic Separation Head Pulleys
