Our magnetic separation systems

WHIMS: Wet High Intensity Magnetic Separator

Global Fourth-generation Vertical Ring High Gradient Magnetic separator (Oil-water complound cooling)

Application:

This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin in order to remove impurity iron and to purify them.

Working principle:

This type of Vertical Ring High Gradient Magnetic separator uses a wholly sealed oil cooling circulating device: through this device process water goes through a oil-water heat exchanger used to remove the heat generated by the magnetic separator’s coils. 
The windings coil generates a magnetic field through the upper and lower yokes: a vertical ring can rotate according to the required direction. When the magnetic separator is working, the hopper is fed by the feeding tube with a pulp that flows through the rotating rings, along with the gap of upper magnetic poles. An induction magnetic matrix composed by high permeability stainless steel rods generates an high gradient magnetic field.

Pulp enters in contact with the lower part of the rotating ring and the magnetic matrix surface attracts magnetic particles. Due to the ring rotation the magnetic minerals are transferred to the nonmagnetic area of the ring and are discharged to the upper hopper by the water flow. 
The non magnetic particles are moved down to the lower hopper following the gap of the lower magnetic pole and the magnetic separation of magnetic minerals is completed. At this point the pulsating box is activated causing the pulp shaking up and down in order to remove impurities and improving the concentration of the pulp.

HMF Electromagnetic filters

The HMF electromagnetic filters are used in wet process separation of para-magnetic minerals found in quartz, feldspar,silicates, calcium carbonate and kaolin. The flow-rates are engineered in accordance with customer requirements.

These are the most technologically advanced magnetic systems that we can offer and can reach a power of 20,000 Gauss.

The flow rates are engineered according to customer requirements.

Here are some examples:

  • 1500 Gauss; viscosity 500 max + 50 micron ferromagnetic
  • 2500 Gauss; viscosity 500 max – 50 micron iron;
  • 5000 Gauss; viscosity 1000 max;
  • 10/20.000 Gauss; viscosity 1000 max;

Overband “Shark” and “O.va” models

Most older generation magnetic belt conveyors were fitted only with ferrite magnets.
Our Overbelt “Shark” model has a specific combination of ferrite and neodymium magnets: what is the advantage for you?

The possibility to reach more than 5507 Gauss magnetic power in contact with the rubber magnetic belt and a total weight up to 10% lighter than a common Overbelt.

ATTENTION, PLEASE: the performances declared above are not only nominal (as often happens in this business, where many companies guarantee magnetic performances calculated approximately or under non-operating conditions).


Vulcanized overbelt strips are extremely robust, providing greater wear resistance to the belt (normally the weaker part of the overbelt).

To provide an additional wear resistance, we reinforced the side structures (sometimes severely stressed by the continuous use of grinding machines or by extreme working conditions or by weather conditions) and the diameter of the shafts (some customers told us they have even exaggerated).

“Tiger” MAGNETIC PULLEYS

“Tiger” magnetic pulleys are ideal tools for wide-ranging deferrization of sandy materials.

The “Tigers” also can easily capture paramagnetic materials (hematite, muscovite, biotite, ilmenite…) and they are particularly suitable for iron removal from very thin particles (0.1 to 0.8 mm).

  • Input materials: feldspar and glass with an iron grade of 1,450 ppm;
  • Separated material: iron 850 ppm
  • Reduction: 41%.

With a diameter of 300 mm and a working height of 1500 mm, our “tigers” have a higher capacity than lower heights and diameters machines: this feature, combined with the exceptional magnetic power (12,310+ Gauss in contact wit the surface), allows our magnetic pulley to practically catch any magnetic particle or paramagnetic mineral.

Nothing get past it.

MAG: DRY MAGNETIC SEPARATORS

MAG 1.10/15 & MAG 3.10/15 magnetic separators machines are ideal devices to deironing a wide range of sand materials.

Paramagnetic minerals (hematite, biotite, ilmenite, etc…) are simply captured by “TIGER” PULLEYS’s powerful magnets.

MAG 1.10/15 & MAG 3.10/15 magnetic separators are particularly indicated for the iron removal of fine particle size products (typically from 0,1 to 1,8 mm).


3 SEPARATION STAGES

Three neodymium magnetic drums that drag the same number of belts: three successive stages of separation for effective iron removal.

The first stage is fed from the hopper integrated on the machine: the magnetic component of the material is retained in correspondence of the magnetic drum.

Depending on the peculiarity of the mineral to be processed and on the required magnetic separation, our machines MAG. 1-10/15 & MAG 3.10/15 can be implemented from three to four magnetic passages.

On our machine can be instaled rollers with a 100 mm diameter and 300 mm diameter with working heights going from 1.000 to 1.500 mm. In order to meet the specific needs of customers, MAGNETENSE is able to produce rollers with diameter bigger than 300 mm.

PLV2 MAGNETIC PLATES

Thanks to the surface treatment we give to our plates, we can assure a significant step forward from the wear resistance point of view (as well as from the aesthetic point of view).

But the most important feature of our plates is certainly the separation efficiency (on average 15%-20% higher than the old systems).

Our “PLV2” are also equipped with a magnetic shielding which avoid workplace accidents.
