Rare EArth Roll Separator-Jupiter Magnetics Private Ltd.-Delhi

Jupiter Rare Earth Roll Separator is one of the world’s highest-intensity, permanent magnetic separators used to purify dry minerals and waste materials.  The

rare Earth Roll Separator removes ferrous particles and weakly magnetic minerals from non-metallic minerals.

The Rare Earth Roll Magnetic Separator is a two-pulley conveyor system with the head pulley constructed out of alternating rings of Neodymium Iron Boron (NeFeB) Rare Earth Magnets and steel pole pieces.

The ultra-strong magnetic head roll of the Rare Earth Roll enables the separation of ferrous and weakly magnetic minerals such as mica.

The Rear Earth Roll is often preferred to other high-intensity magnetic separators as the magnetic field is produced with permanent magnets and not electromagnets.  This significantly reduces both operating and capital investments costs.

 

Operation

In operation, a dry non-metallic mineral mix, sized between 75 micron and 15mm, is fed evenly and thinly via a Vibratory Feeder onto a short-centered and thin conveyor belt.  As the material moves into the separation zone of the magnetic head pulley, magnetically-susceptible minerals are attracted towards the high intensity steel poles.  Non-magnetic material continues to flow in a normal trajectory, whilst the trajectory of minerals affected by the high-strength magnetic field is altered.  With a carefully positioned splitter, the two fractions – magnetically susceptible minerals and non-magnetics – are separated from each other. 

Models

The Rare Earth Roll Magnetic Separator (RE Roll) is available in three diameters:

  • 75mm

  • 100mm

  • The different diameters enable an increased capacity per meter or an improved separation performance.  This is due to the longer dwell time in the magnetic field.

The maximum width of a Rare Earth Roll is 1000mm.

Applications

The Rare Earth Roll Magnetic Separator  was originally developed to purify dry non-metallic minerals.  However, the ultra-strong magnetic properties have more recently been utilized in recycling applications such as purifying plastic waste and in the recycling of batteries.

The optimum particle size for the RE Roll is between 75 micron and 15mm, although it is important to maintain a tight particle size distribution to maximize separation performance.  Specific applications include:

  • Mineral Processing

    • Feldspar

    • Silica Sand

    • High purity quartz

    • Garnet

    • Talc

    • Abrasive and refractory minerals including Corundum

    • Beach Sands (ilmenite, etc)

    • Fine iron ores

  • Ceramics

    • Removing free fine iron from Spray Dried Ceramics;

  • Recycling

    • Cullet (crushed glass)

    • Granulated steel slag

    • Granulated plastic waste

  • Plastics

    • Removing plastic beads containing fine iron spots
