HPGR (High Pressure Grinding Rolls) have become a critical technology in mineral processing due to their energy-efficient high-pressure grinding mechanism. One of the most important wear parts in HPGRs are the carbide cheek plates, which are positioned on the sides of the rolls to prevent material leakage and protect the roll tires from abrasive wear. These cheek plates are typically made of tungsten carbide studs embedded in a steel matrix, offering exceptional wear-resistant materials with low coefficient of friction and outstanding ability to withstand extreme mechanical loads and high temperatures (often exceeding 100–150 °C during operation). The mechanical properties of these carbide composites — high hardness, compressive strength, and toughness — allow them to resist permanent deformation under the intense pressures of high-pressure grinding rolls while maintaining dimensional stability and long service life. In industrial applications ranging from cement clinker to hard-rock mining, selecting the right types of material for cheek plates is crucial for cost-effective operation, as premature failure leads to expensive downtime and replacement costs. Additionally, modern production processes for these wear plates increasingly focus on sustainable raw materials and lower environmental impact, helping the mining industry reduce its overall ecological footprint while delivering reliable, high-performance wear parts that play an important role in ensuring continuous and efficient HPGR operation.
Conclusion
Custom tungsten carbide cheek plates represent a significant advancement in HPGR technology, offering mining operations substantial improvements in efficiency, productivity, and total cost of ownership. The ability to tailor material properties and geometries to specific ore characteristics makes this solution particularly valuable for operations processing abrasive ores.
