Permanent drum magnetic separator can dry and wet magnetic separation. wet drum magnetic separator feeding materials from the bottom, but dry drum magnetic separator feeding materials from the top. Wet Permanent Magnetic Drum separator is a kind of magnetic separator often used in iron ore concentrators.

For dry material, 20 mm and coarser the belt drum type of separator, BSS or BSA, is preferred. For dry material finer than 20 mm the dust house enclosed drum separator, model DS, is …

For a dry high-intensity drum magnetic separator (DHIDMS), its magnet system was generally designed into an extruding magnetic structure, to improve the magnetic field intensity and gradient on the drum surface; and in this way, it is applicable for the separation of weakly magnetic ores and for the purification of non-metallic ores, at ...

Dry permanent magnetic drum separator is the dry magnetic separation equipment that realizes separation of different magnetic materials by using the magnetic field generated by rotation of the permanent magnetic system in the drum. Dry permanent magnetic drum separator can be in single-drum type or multidrum type. Its structure consists of the ...

The separators have modular design with several frames and process tank designs using a common magnetic drum for ease of selection of the best machine for each individual application. ... The dry models are intended predominantly for material 2 to 200 millimeters in dry or nearly dry state like crushed iron ore.

Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not ...

In recent decades, several kinds of dry magnetic separators were developed and reported effective for the pre-concentration of low-grade iron ores (Baawuah et al., 2020, Zhang et al., 2011, Zhao et al., 2017), and they have different magnet designs and may produce different separation characteristics.For instance, a dry magnetic separator with magnetic field …

Low Intensity Dry Drum Magnetic Separator The Low Intensity Dry Drum Magnetic Separator is used in the primary or rougher stages to improve the feeding grade of material to the next stream processing. It is applied in automatic continuous concentration of magnetic ores, or removal of magnetite from fly ash, purification of ground slag, foundry sand, cement and minerals.
