Semi-closed magnetic drums MBO

The MBO is designed for bulk materials of a coarser or bulkier fraction — particularly wood chips and similar materials that could cause blockages when passing through the standard fully enclosed MBZ design. The semi-closed housing allows material to pass freely without clogging, while the MBZ is better suited for finer or dusty bulk materials. If you are unsure which solution is right for your material, we are happy to carry out free testing within three days.

We offer magnetic drums MBO in three diameters: 304 mm (capacity up to 105 m³/h), 406 mm (capacity up to 200 m³/h), and 506 mm (capacity up to 285 m³/h). Working widths range from 300 to 1,300 mm and the magnetic induction at the drum surface reaches 4,300–4,800 G depending on the selected diameter. We advise on the exact model selection individually according to your line parameters.

The MBO drum captures ferromagnetic contaminants from 0.5 mm in size. At the heart of the separator is an assembly of crescent-shaped magnetic cores around which the outer stainless steel shell with strip carriers rotates — this principle ensures continuous separation even when the material is heavily contaminated with metallic impurities. The separator is fitted with ferrite or neodymium magnets according to the demands of the specific application.

The semi-closed housing of the MBO separator is designed for direct connection to a conveyor system without interrupting the production cycle. Separation is continuous: metallic impurities are captured on the drum surface and automatically fall away beyond the drum axis into the ferromagnetic contaminant discharge chute. Every delivery includes on-site installation, commissioning, and operator training.

We provide a 5-year warranty on magnetic drums MBO. We offer warranty and post-warranty service and free material testing on our equipment, with results guaranteed within three days. We handle the entire project from initial assessment through custom manufacturing and installation to long-term operational support.

MBO drums are used primarily in recycling and waste processing, the wood processing industry, food production, plastics processing, mining and mineral processing, and the manufacture of industrial ceramics and glass. They protect downstream machinery — presses, crushers, mills, and shredders — from damage caused by metallic impurities in the material.
