Quarries process thousands of tonnes of solids and slurries; a necessity in order to access the valuable iron, nickel, cobalt and associated alloys. Given that these materials often have magnetic properties, the quality of the final product is at risk.

The answer? Pipe coils that can detect any ferromagnetic content in solids or slurries.

Coils are instruments that use alternating current to identify ferromagnetic content.

This article will take a look at what pipe coils are, where they can prove especially effective and the way to take advantage of the systems.

What they are and how they work

Coils are instruments that use alternating current to identify ferromagnetic content. In most quarries, they'll be installed in the best positions to detect this content. For example, on or around pipes or alongside conveyor belts.

Modern pipe coils usually come into two distinct configurations, and each is better suited to particular applications.

Choosing a coil

The two coil configurations below are best suited for use in quarries, and in the wider industrial sector. Of course, in order to identify the most suitable type it's best to reach out to an expert like SRO Technology.

Encircling coils

Perfect for the in-line inspection of products, these encircling coils identify ferromagnetic content as the materials passes through the centre via conveyor.

They're quite simple in principle: the test coil becomes excited by an alternating current which induces a flow of eddy currents around the material passing through the coil. When ferromagnetic content passes through, it causes a change in the eddy current flow. Electronics can then detect this change, and operators take appropriate action.

SRO Technology can manufacture encircling coils for businesses in the industrial sector, with solutions designed specifically for the tough operating conditions of quarries.

Surface probes

This coil type is commonly positioned at a point where the pipe coil's axis is held at a normal distance from the material's surface. These probes can also be obtained in a pancake shape to cover greater surface area.

They can be a more flexible option than encircling coils, but both are excellent options for industrial operations. Surface probes from SRO Technology are durable, capable of extremely high performance and are easy to put in place.

As noted above, taking advantage of expert advice and experience is the best way to ensure coils are set up correctly.

SRO develop robust and reliable coils that are still cost-effective and purpose-built.

Reach out to the experts

SRO Technology are experts when it comes to pipe coils. Thanks to years of experience, SRO can manufacture, install, calibrate and then repair pipe coils with ease. From the initial installation through to when these coils are being operated, expert guidance is never far away.

SRO understand that every organisation will have different requirements when it comes to pipe coils, and that's why there's a focus on site visits to determine which coils are actually most appropriate. This approach can prove particularly useful depending on whether the business is working with solids or slurries, for example.

As for the coils themselves, SRO develop robust and reliable coils that are still cost-effective and purpose-built. Again, whether for solids or slurries they're going to perform the task to the highest possible standard.
