In the cement and mining industries, grinding discs withstand immense compression and grinding forces, making them prone to grooving or edge wear from material friction. This significantly reduces grinding efficiency and increases energy consumption. By utilizing hardfacing technology, wear-resistant welding rods or wires with high hardness, heat resistance, and strong abrasive wear resistance can be applied to the working surface. This quickly fills pits, restores original geometries, and forms a protective layer. Consequently, wear life is substantially extended, downtime for replacements is reduced, and continuous, efficient operation of the grinding system is ensured.
