MillCarb™: we enter a new era of wear protection


After a lot of talk and some secrecy around MillCarb™, the solution was officially launched on 5 April 2018. We specifically refer to it as a solution, as this is exactly what MillCarb™ is. It creates an ideal opportunity for Welding Alloys Group to offer customers a truly engineered and fully optimised welded overlay solution. So far testing in aggressive coal grinding applications has proven that MillCarb™ outperforms all products it has been tested against. These include market-leading ceramic embedded rollers.

What is MillCarb™?

MillCarb™ is a unique multi-layer welded overlay material comprising of ceramic-carbide particles embedded into a hard and wear resistant chrome and complex carbide rich matrix resulting in the ultimate solution to combat wear in coal and cement grinding applications.

The success of MillCarb™ is predominantly rooted in the “How” and not necessarily the “What” of the solution. Through extensive research, development, expert scientific analysis and real-time field testing a welding procedure was derived, ensuring the following aspects of the solution

  • Full repeatability
  • Multi-layer welding up to 20mm thick
  • Area-specific deposition if needed, to ensure ultimate protection in high wear zones
  • A fully re-weldable solution
  • Uniformly distributed ceramic-carbide particles throughout the thickness of the overlay
  • Availability from strategically placed Welding Alloys Integra™ facilities

With MillCarb™, we enter a new era of wear protection for mill grinding components, setting new standards for the cement and coal milling industries.
