Magnetic Separation Equipment
Magnetic Dewatering Trough
The magnetic dewatering trough uses a stationary permanent magnet system inside a slowly rotating drum to agglomerate and retain magnetic particles. It operates on wet feed and discharges a thickened magnetic underflow.
Technical parameters
It is typically installed after roughing and cleaning magnetic separators. This position reduces the water load on downstream thickeners, filters, or transport systems, and it strips away fine nonmagnetic slimes that would otherwise dilute the final concentrate.
The model table lists multiple trough sizes, each with a drum diameter, outlet diameter, processing capacity, and weight. Larger drums accept higher flow rates but require more floor space. Selection matches the trough’s capacity to the expected magnetic concentrate stream from the upstream separators. Outlet diameter dictates the discharge aperture size, which affects underflow consistency.

Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
To size a magnetic dewatering trough, confirm the solids throughput of magnetic concentrate from the upstream circuit and its particle size distribution. Define the feed pulp density and the maximum acceptable magnetic solids loss to overflow. Mineralogy matters: ores with a wide gangue-to-magnetite intergrowth may need prior regrinding to keep slime rejection effective.
