The BJ Magnets’ Wet Drum Magnet consists of a stationary, shaft-mounted magnetic circuit completely enclosed by a rotating drum. The magnetic circuit is typically comprised of several magnetic poles that span an arc of 120 degrees. When material is introduced to the revolving Drum shell, concurrent at the 12 o’clock position, the non-magnetic material discharges in a natural trajectory. The magnetic material is attracted to the Drum shell by the magnetic circuit and is rotated out of the non-magnetic particle stream, in which case the magnetic material is discharged from the Drum shell when it is rotated out of the magnetic field.

BJ Magnets’ Magnetic Wet Drum Separator, available with or without housing, is used for applications where a high degree of fine or slurry product purity is required. Such applications are also for separation processes of materials like fine grained red mine (hematite) limonite, manganese ore, ilmenite and other kind of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin, in order to remove impurity iron.

Our types of Wet Drum Separators are effective in removing very fine ferrous particles and strongly paramagnetic particles. Other than iron ores, they are good for recovering magnetic or ferrosilicon in dense media plants as well as for decreasing utility requirements and delivering large savings to operational expenditure.

BJ Magnets’ Wet Drum Magnets combine the attributes of a high-strength permanent magnetic field and a self-cleaning feature. They thence can be considered for the application of product productivity increase, especially where product purity is highly essential. This separator is effective in treating process streams that contains a high percentage of magnetics and can produce a “clean” magnetic or non-magnetic product.

Built in several sizes of up to 4.3 m diameter by 6 m long, with capacities of up to 450 t h−1 and treating feed particles of up to 30 cm in diameter; the separation is accomplished by the continuous removal of the sink product through the action of lifters fixed to the inside of the rotating drum. The lifters empty into the sinks launder when they pass the horizontal position, and the float product overflows a weir at the opposite end of the drum from the feed chute. Longitudinal partitions separate the float surface from the sink-discharge action of the revolving lifters for effective and effecient separation.

Permanent magnetic drum separator

Which consists mainly of a permanent magnet system, a rotating drum, a separating chute, a feed tank, and a flushing pipe – has magnetite separation with the magnetic field intensity on the surface of the drum of between 0.1 and 0.4 T. However, for other applications, the intensity may reach as high as 0.8 T. Designs are bespoke done according to the relevant client’s specifications needs.

When the iron ore slurry passes through the separating chute, magnetite particles from the slurry are attracted by magnetic forces to the surface of the drum, while gangue minerals are dragged down by gravity and water flow. These magnetic particles are then brought by the rotating drum to the top where the magnetic field is weak and close to zero, and they are then flushed away from the drum as an iron concentrate.

There are several types of permanent magnetic drum separators used for roughing and cleaning and for fine and coarse particles. They may look different, but they all work on the same principle.
