The vertical roller mill (VRM) is the core equipment of a cement plant, responsible for the grinding of raw meal, coal powder, or clinker. Under high-speed operation and extreme squeezing pressure, the mill table liners and roller surfaces endure severe abrasive wear. Utilizing chromium carbide overlay (CCO) wear plates for the air guide ring or housing liners, combined with hardfacing repairs on the grinding rollers, can effectively maintain the grinding geometry, minimize vibration, and substantially boost production capacity.
