Why Mining Companies Should Use Magnetic Particle Testing

Many experts and professionals think that magnetic particle testing would be the best way for mining. I agree with them. That is because magnetic particle testing has many significant advantages, and it is very much worthy of trying. So, all mining companies should go for this method. Now, to more detail why they choose magnetic particle testing, you should read the below article.

What Are the Advantages of Magnetic Particle Testing?

You know what? All mining companies should use magnetic particle testing method. That is because it has many advantages for mining and is non-destructive. However, it is speedy and generally straightforward. It gives prompt signs of imperfections. It shows surface and close-to-surface imperfections, and these are the most genuine ones as they concentrate stresses.

What are the applications of magnetic particle inspection?

Applications for attractive molecule review include testing welds, castings, devices, bar-stock, and other parts for quality control, surface uprightness, code conformance, and pre-machine screening. It also has many other suitable applications. And, since it has many advantages and great uses, it can be used for good purposes like mining.

Which is the advantage of using direct current in magnetic particle inspection?

What is the upside of involving direct current in lovely molecule review? Clarification: Sub-surface imperfections can likewise be recognized by utilizing direct current stock because of their higher infiltration. In any case, demagnetization of the example becomes troublesome.

What is the basic principle of magnetic particle testing?

The standard of the technique is that the example is charged to create attractive lines of power, or motion, in the material. Assuming that these lines of power meet brokenness, for example, a break, optional attractive posts are made at the essences of the break.

What companies use magnetic particle testing?

These are the companies that use magnetic particle testing:

  • MQC Labs, Inc.
  • Mitchell Laboratories.
  • Techmetals, Inc.
  • Pacific Magnetic & Penetrant Co. Inc.
  • Accu-Chek, Inc.
  • Imagineering Finishing Technologies.
  • Machine Specialty & Manufacturing, Inc.

How do you perform magnetic particle inspection?

You can follow these steps:

  1. Actuate an attractive field in the example.
  2. Apply attractive particles to the example’s surface.
  3. View the surface, searching for molecule groupings brought about by abandons.
  4. Demagnetize and clean the example.

Is it standard for magnetic particle inspection?

Yes, it is. However, ISO 9934-1:2015 determines general standards for the attractive molecule testing of ferromagnetic materials. Attractive molecule testing is essentially material to the location of surface-breaking discontinuities, especially breaks.

Is magnetic particle testing safe?

Eye security ought to be worn by the administrator to make preparations for the aggravating impacts of residue particles and arcing. Individual defensive hardware should be worn to shield against the possible skin disturbance from the powder.

Why is it necessary to Demagnetise the workpiece after MPI?

Since MT is performed by adequately charging DUT, then, at that point, ships off post-process in the polarized state. For the situation where the impact of a polarized state turns into an issue in the post cycle. For instance, the bond of iron powder or handling, it is essential to demagnetize DUT to send it.

What is the real test for recognizing a magnet?

Repugnance is the surest trial of the magnets because an attractive substance additionally has appealing property. Shock is the surest test because any substance made of iron, nickel, cobalt will likewise have fascination; however, it will not have an aversion.


I hope now it is clear why mining companies should use magnetic particle testing for their mining projects.
