CMC Tecnologia has been consolidating its position as a reference in anti-wear engineering solutions with concrete and long-lasting results. A clear example of this is the success case at SIBELCO, a Belgian multinational specialized in industrial minerals, which relied on CMC’s expertise to optimize the operation of its continuous mills.

⚙️ The challenge

In 2021, SIBELCO’s Brazilian unit faced accelerated wear in one of its quartz mills, with a capacity of 28 tons per hour. The deterioration of the previous lining (not supplied by CMC) put process efficiency at risk and increased the chances of unplanned downtime.

🛠️ The CMC solution: HARDTEC® applied with precision engineering

From the very first contact, the CMC team acted with a strategy focused on performance and durability. The work followed a continuous line of scheduled maintenance, technical application, and preventive inspections, always using the HARDTEC® ceramic lining, recognized for its resistance to abrasion and corrosion.
