This 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 trialled in many applications. 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.
Without DURA-SLIK™, magnetic separators are more likely to experience rapid deterioration, 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 a product recall and reputation damage.
DURA-SLIK™ is accepted by FDA as non-toxic.
Rob Baker, Operations Manager of MAGNATTACK™ Global, says that “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 says “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.
DURA-SLIK™ is subject to extensive IP rights.
