Over Band Magnetic Separator (OBMS)

Over band magnetic separator is specifically designed for the protection of the machineries like shredders and crushers by eliminating abrasive ferrous bits from the material to be proceeding. As the name shows, over band magnetic separator situated over the vibratory feeders or inclined planes from where the material is passed for the further procedure in production line. Due to strong magnetic field, all kinds of ferrous impurities are being captured and collected separately. It improves the product quality as well as prevent damage from these contaminants.

A drum containing two different U-section pieces is arranged by the bearings of the drums. Shafts are provided to drums. It is also provided with geared motor and electrical motor. Vee-belt is drove through the reduction gear. In order to offer high magnetic field, magnets are made from stroncium ferrite magnets of high intensity. To cover the magnetic pole a non-magnetic stainless steel plate is used.

Continuous Operation of Cross-Belt Over Band Magnetic Separators

Over band magnetic separators (OBMS) are designed for continuous, automatic extraction of large volumes of tramp metal from material flows transported on conveyor belts. Positioned cross-belt or inline over the head pulley, these separators utilize a heavy-duty permanent magnet or electromagnet to lift iron contaminants out of the conveyor bed. A revolving belt around the magnet housing automatically discharges the attracted metal into a separate chute, ensuring uninterrupted production.

Built with robust structures and high-gradient permanent strontium ferrite or neodymium magnets, our over band separators deliver deep magnetic penetration. This heavy-duty system is essential in rugged industries such as municipal recycling, aggregate crushing, coal power plants, cement manufacturing, and metal casting foundries to protect equipment and optimize raw material recovery.

FAQs About Over Band Magnetic Separators

1. What is the role of an over band magnetic separator (OBMS)? + It is a self-cleaning magnetic separator installed above conveyor systems to continuously extract and discharge tramp iron from bulk material streams.
2. How does the self-cleaning mechanism of an OBMS work? + An electric motor drives a continuous rubber or armored belt around the magnet. Ferrous particles are pulled to the magnet, carried away by the moving belt, and dropped outside the conveyor trajectory.
3. Can the suspension height of the overband magnet be adjusted? + Yes, the separator is suspended via adjustable turnbuckles, chains, or hoist assemblies to optimize the distance between the magnet face and the conveyor belt.
4. What is the difference between permanent and electromagnetic over band separators? + Permanent models use natural strontium ferrite or neodymium blocks which require no electricity, whereas electromagnetic units use powered coils to generate stronger magnetic fields for deeper material beds.
5. What industries rely on over band separators? + They are heavily utilized in mining, coal power generation, municipal solid waste recycling, glass manufacturing, wood processing, and aggregate quarries.
6. Are vee-belts and motors included with the separator? + Yes, our over band separators come fully integrated with high-efficiency geared motors, drive pulleys, vee-belts, and robust steel frames ready for installation.
