General Specification:

Flux density: 1400 ± 200 gauss.
Attraction Distance: For M10 x 100 mm Length MS bolt Upto 250mm/10inches, If the free path is available.
Height of Suspension magnet is 154mm
The maximum operating temperature of 250 Degree C.

How does it work?

Suspended Magnet is placed over the conveying belts carrying the material. This system arrests Ferromagnetic materials from the distance of 300mm/12 inches from feed material which is transported through the production process.

Construction

Suspended magnets are generally in big sizes depending upon the width and speed of the conveyor belt. They are provided with eye bolts, D shackles and sling chains with turnbuckles for adjustments while mounting.

Note:

The above attraction distances are taken at a point below the geometrical center point of the suspended magnet assembly.
The above trial results are obtained when the free path is available for tramp iron particles.
The above chart is given for reference. One may get a deviation of 1 to 2 inches in attraction distances depending on actual site conditions.
The MOC of rollers & frames of the conveyor should be of nonmagnetic material (S.S.304), otherwise, all the magnetic flux will pass through the conveyor & it will reduce the efficiency of the magnet.
It is advisable to use the suspended magnet & magnetic pulley in combination for effective to the removal of tramp iron.

FAQ for Suspended Permanent Magnet

1) How much kg of iron it can lift & from what distance?
Ans - The attarction height of the magnet depends upon the weight & shape of the tramp iron. Please refer the weight Vs attarction distance chart for different type of objects for each magnet model.

2) Is it require power supply for operation?
Ans - No it made-up of permanent magnets hence do not require power supply.

3) Is there any demagnetisation facility available to remove trapped iron?
Ans - No. The trapped iron have to remove manually only.

4) Is magnet comes with chain slings ?
Ans - Yes we will provide 4 Nos of chain slings alongwith the magnet.

5) How should i select the magnet size?
Ans - Please select PML standard model as per size of the conveyor belt at your end.

6) What type of iron contamination it can lift?
Ans - Suspende magnet is used to separate tramp iron like bolts, broken spanners, angles, rod, nuts etc. Please refer the weight Vs attarction distance chart for different type of objects for each magnet model.

7) What will be the life for magnet?
Ans - It is a permanent magnet it will not loose its magnetism. Magnet can get demagnetized in two cases, a) When it get damaged. b) When magnet get exposed beyond specified operating temperature. But magnet can loose its magnetism 2% to 3% over the span of 5years.

8) Can we recharge the magnet?
Ans - No. Magnet cannot be recharged.

9) Can we install suspended magnet at height more than 300 mm?
Ans - No, Suspenended Magnet can work efficiently with operating height 300 mm (12 Inches).

10) How we can measure the power of magnet ?
Ans - Magnetic intensity can be checked by gauss meter. We also provide calibration services, which we will be valid for 1year

11) Does it have any effect on human body?
Ans - Magnet doesn't have any effect of human body. The persone who is using heart spacemaker should not go near the magnet as the magnetic field may affect on working of the spacemaker.

12) Is this magnet efficient to remove 100% iron contamination from the material flowing over the conveyor belt?
Ans - It is advisable to use the suspended magnet & magnetic pulley in combination for effective to the removal of tramp iron.
