Conveyor head rollers MV / Magnetic pulleys
A magnetic pulley (sometimes called also a magnetic roller) is a device for automatic and permanent removal of magnetic iron metals from inert materials.
Installation of the pulley magnet
The key part of the machine consists of a set of ferrite or neodymium NdFeB magnets and of an external drum from stainless steel that revolves on a shaft together with the magnetic cores. The magnetic pulley is usually an integral part of a belt conveyor (unlike the magnetic drum).
How does the magnetic head pulley work?
The ferromagnetic pieces (transported on the conveyor belt) are captured by the strong permanent magnets and dragged on the surface of the pulley beyond the magnetic axis of the drum where they fall off (already before that the non-magnetic particles fall off due to gravity).

Recommendation
The magnetic field of the separation pulley is about 100 mm high, so it is advisable that the layer of the substance on the band should not be higher than 80 mm. In case of a high layer of the transported stuff we recommend to combine the use of the magnetic separation pulley with the application of our overband separator or our magnetic plate.
Advantages of the magnetic pulley
The magnetic pulley is easy to install and maintain, the materials used for its production (stainless steel, set of permanent ferrite or neo magnets) as well as its robust design provide for a long-term solution to separation problems.
The application of ferrite magnets arranges for nearly unlimited working life, however, if you need higher magnetic force we recommend that the drum is fitted with extremely powerful neodymium NdFeB magnets from rare earth ores (especially in case of the separation of small ferromagnetic particles from materials of worse bulk properties).

The conveyor head roller MV becomes a direct component of the belt conveyor and replaces its head or pressure roller — unlike the MBZ/MBO drum, it therefore requires no separate housing unit beside the conveyor. Inside the roller, a magnetic core is fixed in place while the shell rotates around it; ferrous particles are carried past the roller axis and separated from non-magnetic material, which falls away earlier under its own weight.
The magnetic field of the conveyor head roller MV reaches approximately 100 mm from the surface — at greater layer heights, particles in the more distant zones move out of range of the field and separation will be incomplete. We therefore recommend that material height does not exceed 80 mm; if in doubt, we will carry out a free test of your material with a guaranteed turnaround of three days.
We supply MV rollers in eight diameters from 154 to 609 mm with a magnetic field of up to 4,200 G and throughput capacities from 15 to 220 m³/h depending on the selected model and belt width of 200–1,500 mm. We adapt production to the parameters of your line; some models are available immediately from stock.
The ferrite core has a virtually unlimited service life and is suitable for standard separation of coarser iron particles. The neodymium core (NdFeB) generates a stronger magnetic field and captures even fine or weakly magnetic contaminants — we recommend choosing it wherever ferrite is insufficient or where maximum purity of the output material is required.
MV rollers are used primarily in the wood processing industry and wood waste recycling, mining and construction, plastics and rubber processing, the ceramics and glass industry, and food processing. They protect downstream equipment — shredders, mills and screens — from damage caused by metallic contaminants in the material.
We provide a 5-year warranty on the magnetic core of MV rollers and offer both warranty and post-warranty service. Every delivery includes on-site installation, commissioning and operator training; we carry out free tests of your material on our equipment with a guaranteed turnaround of three days.
Which industrial branches can the magnetic head pulley be used in?
The permanent magnet systems simplifies the separation of ferrous particles, allowing for automatic recovery without production stoppage. At the same time the magnetic roller protects the subsequent machinery (e. g., shredders, mills, grinders) from breakage. The magnetic pulleys find use in recycling and mining as well as in wood and plastic industries.
