PERMANENT MAGNETIC DRY DRUM SEPARATOR
Magnetic Drum Separators for dry applications suitable for free flowing solids, minerals etc.
Key Applications
- Upgradation of non-ferrous minerals by removing magnetic impurities (eg. Silica, Feldspar, Calcite, Quartz etc., Chromite).
- Magnetic concentration of metallic minerals (eg. Ilmenite, Garnet, Sponge iron).
- Pre-concentration of coarse particles (Magnetite).
- Scavenging moderately magnetic minerals prior to feeding to a WHIMS (hematite iron ore).
- Particle Size Range: 0.050 mm to 50 mm.
Available Diameters and Width
- Ø 305; Ø 381; Ø 610 and Ø 915 mm
- Widths starting from 150 up to 3000 mm.
Configuration/Features
- With electromagnetic vibratory feeders with provision for variable feed control.
- Rubberised roll feeders with variable frequency drive to control feed rate.
- Gravity fed hoppers for small capacity and small width drums.
- Complete dust protected housing in mild steel / stainless steel.
- Multiple drums in a single housing.
- Multiple split discharge chutes.
- Magnetic re-run or Nonmagnetic re-run as desired.
- Low intensity drums: available with peak magnetic intensities of 1000-2000 gauss on drum surface.
(Magnets used in these circuits are strontium ferrite / ceramic magnets.) - Medium Intensity Drums: available with peak magnetic intensities of 2500-7000 gauss on drum surface.
(Nd-Fe-B rare earth magnets used in magnetic circuits) - Axially aligned alternating magnetic polarity to produce a sharp separation.
Laboratory Test Facilities
