Usage of Magnetic Separation

All substances are affected in a sense when placed in a magnetic field, though with most substances that the result is too small to be detected.
Materials could be categorized into two classes.
1. Diamagnetic Materials
2. Para magnetic Materials
Diamagnetic are repelled over the lines of magnetic force to some point where the field intensity is smaller.
The forces involved here are very small.
Para magnetic are drawn along the lines of a magnetic drive to points of greater field intensity.

. For the removal of tramp iron in demanding and intermediate- crushing circuits, as a safety to the crushing machines.
. Because of its concentration of magnetite ores.
. For the concentration of iron ore additional than magnetite, following preliminary transformation of iron minerals to

synthetic magnetite from suitable Roasting.
. For the removal of small amounts of iron ore minerals from Ceramic raw materials. Production of genetically converging magnetic field.
. Even feeding of ore particles as a flow or sheet.
. Control of speed of passing of ore during the magnetic area.
. Avoidance and correction of occlusion or nonmagnetic material between   or inside magnetic flux.
. Provision of acceptable means for disposing of separated products.
. Provision for production of a middling.
. Elimination or loss to a minimum of transferring(sporting) components.  IMPORTANT TYPES OF MAGNETIC SEPARATOR1. EDISON

. EDISON SEPARATOR Edison separator is made up of the bar magnet. The ore as thin streams falls in front of their poles,

susceptible particles being deflected inwards &non susceptible particles continuing to fall undeflected. WPE Process Equipment manufacture high quality vibratory screening machine in Australia. This separator was not wholly successful because of the inability of control stream of strong in a thin sheet, & due to the absence of control over the rate of this falling particles.
Magnetic drum separators are important magnetic separators that remove ferrous metal from dry mass products in free-

flowing processing systems.
They are self-cleaning unit consisting of drums and housing normally of stainless steel. The magnets utilised by magnetic drum separators are either ceramic magnets or rare earth magnets. The magnetic drum separators can be found both in single or double drum setup.

How it Works?

The rotatory drum from the magnetic field captures the ferrous tramps whereas non-ferrous falls loose from the drum to the cleaned material flow. Since the drum rotates, the ferrous alloy so caught is carried past the diverter and released outside of the magnetic field. Types Magnetic drum separators are of distinct kinds such as:
•Electro drum separators•
Applications The magnetic drum separator is excellent for splitting iron particles from granules & powders it’s commonly

used in the following industries:•
Glass•Ceramic•Chemical•Fertilizer•Plastic•Food industry•Iron and metal slag therapy•Reduced pyrite ash split•Calcined ilmenite production Metal powder production
Ball Norton Separator Unlike most charismatic separators which are utilised to eliminate relatively small quantities of metal, the Ball Norton Separator is designed to handle considerable quantities of insulation – removing other undesirable elements. A unique mixture of alternating magnetic rods and vibratory communicating works to wash out the magnetic material. Applications include foundry shot, crushed borings, slag and magnetic ores.
The way that it Works? The fabric is discharge on the belt from the feeder. The magnetic rolls enveloped from the conveyor. The para and also Ferromagnetic ingredients remain stuck to the belt whereas on magnetic ingredients passes freely in the close of the conveyor.The roller type magnetic separator has wide program industries and mineral technology. The separator utilises high powered rare earth magnets with quite low dimensional tolerance. The other components of the machine are conveyor along with vibratory feeder. The charismatic rolls are available in distinct widths along with magnetic strength
Applications Roller type magnetic separator finds software in the subsequent areas like
•Glass businesses•Abrasive refractory•Quartz cleaning•Upgrading of graphite•Recovery of metals in slag elimination of ferrous silicates.

Chemical sectors Gravity feed magnets split ferrous tramp metal through gravity method. These magnets are constructed out of stainless steel and are available in stainless steel construction. The gravity magnet comes from different shapes and sizes and is great for narrow chute applications. Gravity feed magnets are typically utilised in vertical flow method.
Applications Gravity magnetic separators have different industrial and industrial commercial usage. They’re implemented in

industries such as:
•Food sector•Chemical industry•Grain processing industries
Pharmaceutical sectors
Magnetic coolant separator is a device which cleans the coolant liquid of quite fine ferrous particles.It removes the iron chips in the milling or grinding liquid. It’s light and a compact structure having strong magnetic power which can remove very good ferrous particles.For precise grinding operations, uninterrupted stream of oil is the must.The Fluid magnetic separator ensures the uninterrupted flow of the liquid.
Attributes Wet drum magnets possess high magnetic retrieval and discharge. The feed slurries recover the magnetic. Available in single or multiple drum applications. Recover magnetic solids in as clean a magnetic concentrate as you possibly can. Permanent magnet assembly removes coil burn-outs . The magnet/rod elements are formed into a mild steel shaft. The spiral is made from heavy stainless steel for long service everyday lifespan. Wet drum separators are available in the different configuration like only wax, double-blind and multiple drums. In dual blind two separators are organised back to back using a frequent feedback.
