Magnetic Drum MB

The magnetic drum MB is installed as a standalone unit – beneath a belt conveyor or hopper, or inside a housing – and the installation does not require any modification to the existing belt conveyor. The magnetic pulley MV, on the other hand, is integrated directly into the belt conveyor, where it replaces the head pulley. The choice depends on whether you want to integrate separation into an existing conveyor or handle it as an independent unit.

The ferrite drum MB F is suitable for capturing larger ferromagnetic contaminants and is more cost-effective – the magnetic flux density on the shell ranges from 1,100 G (diameter 154 mm) to 1,500 G (diameter 304–609 mm). The neodymium drum MB N achieves 3,300–3,800 G on the shell and captures even very fine ferromagnetic particles from powdered or less permeable materials. We recommend consulting our technician when choosing between the two variants – they will assess the type of material, its granulometry and the required separation efficiency.

We offer six diameters – 154, 204, 304, 406, 506 and 609 mm – in working widths from 150 to 950 mm. Capacity ranges from 15 m³/h for the smallest variant (MB 154 F 200) up to 220 m³/h for the largest (MB 609 F 1000). For correct dimensioning, we take into account the type and grain size of the material, required throughput and the type of contaminants to be captured.

The magnetic drum MB is self-cleaning: the shell rotates around a stationary magnetic core and stainless steel carriers sweep the captured ferromagnetic contaminants past the drum axis, where the magnetic field ceases to act and the contaminants fall away by gravity into the collection chute. Separation thus takes place continuously without interrupting the production process and without the need for manual cleaning.

For applications involving abrasive material, we modify the drum design so that the shell can be replaced by the operator through an access opening in the housing – without dismantling the entire drum. On special request, we manufacture the shell from wear-resistant manganese steel, which extends service life in demanding conditions severalfold. The need for a replaceable shell must be specified in advance so that we can adapt the equipment design accordingly.

We conduct free tests of your material on our magnetic separators and guarantee results within three days. Based on the tests, we recommend the appropriate drum diameter, magnet type and working width. Every separator is supplied with a test report containing measured values of magnetic flux density – measured directly on the drum shell, i.e. at the point of contact with the separated material.

We provide a 5-year warranty on magnetic drums MB. We provide service support throughout the entire service life of the equipment – from assessment and design, through custom manufacturing and installation, to commissioning, operator training and authorised service. Our cooperation does not end with the order.

The magnetic drum MB is designed for continuous separation of ferromagnetic contaminants from bulk materials – it is used in recycling and waste processing, the food industry, the wood processing industry, cement plants and lime works. It protects downstream processing equipment (crushers, presses, mills, screw conveyors) from damage by metal objects such as broken machine parts, bolts, nuts or wire.
