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 measurements

Width Diameters
150mm – 3000mm Ø 305; Ø 381; Ø 610 and Ø 915 mm

Configuration

  • 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.
