Magnetic pulley BM
The BM type magnetic head pulley is designed to be built into a belt conveyor instead of the drive drum and is used to separate ferrous metals from bulk materials transported on the belt. The magnetic pulley protects mills, crushers and other process machines against damage caused by tramp metal and is a perfect complement to the over-belt separator. The BM pulley is also used to recover valuable ferrous scrap in waste recycling processes.
The BM magnetic pulley is reliable, very robust and designed for continuous operation. The BM pulley is characterized by high metal separation efficiency. The ferrite or neodymium permanent magnets used in the pulley have high coercivity, which makes them difficult to demagnetize. Therefore, the magnetic pulley has a long service life.

Magnetic head pulley during operation
Versions of magnetic pulleys
- BM-F type ferrite pulley
Made of ferrite magnets with medium magnetic field intensity;
Designed to remove larger metal contaminants from the transported material, such as screws, bolts and other broken machine parts. - BM-N type neodymium pulley
Made of strong neodymium magnets with high flux density;
Designed to remove small metal contaminants from the transported material, such as bearing balls, metal filings, iron oxides and others with a small adhesion surface to the magnet and weakly magnetically susceptible. - BME type electromagnetic pulley
Consisting of a DC electromagnet with a high range magnetic field;
Intended for separating large-sized iron scrap.
The magnetic pulleys we produce are rubberized at the customer's request. We use rubber linings with a "diamond" profile, 6 or 8 mm thick. Due to the possibility of damage to the magnets during vulcanization in the autoclave, the drums are rubberized using the "cold" method using specialized adhesives.
The magnetic pulley can be additionally equipped with spherical roller bearings in dust-proof housings and a cylindrical-bevel gear motor.
Working principle of the magnetic pulley
The material to be separated is transported on a belt conveyor. As the material passes through the head pulley, it is exposed to a magnetic field generated by strong permanent magnets installed in the pulley body. Ferrous metals are captured by the magnetic field and held on the conveyor belt, while the magnetically neutral material falls freely from the conveyor. Metals fall off the belt at the point where the belt no longer adheres to the pulley, either under the influence of gravity or with the help of cleats located on the belt. The efficiency of separation is enhanced by an adjustable splitter placed under the belt conveyor.
Why choose our magnetic pulleys?
Magnetic pulleys from Magnetix are manufactured in many versions for customers all over the world. Pulleys are available in diameters from 100 to 1200 mm and working widths up to 3000 mm using ferrite and neodymium magnets.
An innovative technology of water jet cutting of magnets and yokes has been developed for the production of magnetic systems, thanks to which very high precision of magnet assembly has been achieved, and consequently high power of the emitted magnetic field.
Magnetix ensures an individual approach to each order and a quick completion date, also for serial deliveries for regular customers.
Magnetic pulley price and delivery time
The price of a magnetic pulley depends primarily on the diameter, working width and magnetic material used. Pulleys made of neodymium magnets are more expensive due to the constantly rising prices of rare earth metals. Bearings and drive are selected individually depending on the parameters of the belt conveyor.
The delivery time of the device on order is usually 4 - 6 weeks. We also fulfill orders with an accelerated deadline. Magnetix also has a large warehouse of separators available immediately.
