New DURA-SLIK technology released to reduce abrasive wear on magnetic separators

MAGNATTACK Global has developed, trialled and released an advanced method to reduce rapid wear and damage to magnetic separation equipment.

Rapid wear and damage is especially a concern in abrasive and sticky products such as grain, sugar, lactose, coffee, rice, meat meal, dry pet food and other similar foods. Magnets installed in high-tonnage or fast-flowing product streams are even more prone to such damage.

In simple terms, DURA-SLIK is a hard-densified embedded molecular surfacing which imparts increased abrasion resistance and anti-stick properties to 316 stainless steel. The technology has been developing over a number of years and has been trialled in many applications, with much success. Magnets using the DURA-SLIK technology have been installed in high-tonnage grain applications for over 2 years and show reduced wear of concern, in fact still recording surface strengths of over 10,000 gauss. DURA-SLIK is accepted by FDA as non-toxic.

Without DURA-SLIK, magnetic separators are more likely to experience rapid deterioration and an increase in magnet strength loss, and present dangerous contamination risks to the end products. Should food product be exposed to raw rare earth materials, this could lead to foreign metal contamination, product recall, consumer injury and brand reputation damage.

Rob Baker, Operations Manager of MAGNATTACK Global, said, "Whilst MAGNATTACK magnets have performed well in a variety of harsh installations over the years, DURA-SLIK is an essential value-add, that will extend the longevity of a magnet and help maintain its effectiveness in removing foreign metal contaminants."

On the differences that DURA-SLIK holds, Baker said, "The benefits that DURA-SLIK provides against abrasive wear are very clear when you compare two similar magnet installations where one is a MAGNATTACK DURA-SLIK design and the other is not."

DURA-SLIK technology is available on all MAGNATTACK grate magnets, bar magnets, magnet probes and practically all other magnet or housing surfaces, as an available option on supply where required. It is effective in both dry and wet applications.
