Why belt demagnetisation systems are essential for mines

Mines, pulp processing plants and even food production facilities usually contend with some form of tramp metal, debris that can cause operational disruptions in the best of times and irreparable equipment damage in the worst situations.
Thankfully, tramp metal detection systems alert plant managers to broken excavator tracks, particle contaminants and other rubbish that exacerbate costs. However, these systems are prone to faults of their own, and may accidentally register tramp metal when it doesn't exist.
An overview of belt magnetisation
Splicing steel cord conveyor belts creates non-uniform magnetic fields that can trip tramp metal detection instruments. The cutting and staggered layout of the steel cords is the culprit in this regard, forcing administrators to temporarily suspend operations to check for faults.
This problem can worsen if the conveyor belts in question are distributing material such as iron ore magnetite. As one can imagine, the expenses associated with searching for tramp metal that isn't there can significantly impact a business's competitiveness.
Due to this issue, plant managers install belt demagnetisation instruments to prevent unintentional trips. These contactless devices prevent the disruptions that negatively affect companies' bottom lines.
How do belt demagnetisation systems work?
Eliminating the magnetic fields throughout steel cord conveyor belts involves placing multiple conditioning heads under the carry side of the belt. These components make up the core of the belt demagnetisation system.
VeyTech, which produces the FLUXRITE demagnetisation solution SRO Technology distributes and services, noted the conditioning heads first normalise and then vitiate the magnetic flux. The solution decreases the strength of irregular magnetic fields to the point where the tramp metal detectors won't register the flux.
This means instruments calibrated to identify unwanted debris will continue to function appropriately. In other words, a demagnetisation system won't attenuate rubbish metal that your operations need to be aware of.
Acquiring the correct system
It's imperative that businesses calibrate belt demagnetisation systems according to the requirements of their operations. An instrument located at a pulp manufacturing plant will possess different settings than one installed at a bauxite processing facility.
In recognition of these disparities, SRO Technology installs, calibrates and repairs demagnetisation systems for a wide variety of applications. Our partnership with FLUXRITE enables us to provide our customers with access to some of the most well-developed instruments in the industry.
