Tungsten Carbide Wear Tiles are engineered, plate-like components that are permanently bonded to the interior high-wear zones of a decanter centrifuge bowl and conveyor. They act as an ultra-hard armor, specifically designed to combat the primary failure mode of these machines: severe abrasive wear. As a centrifuge spins at high G-force to separate solids from liquid, abrasive particles (like sand, drilling cuttings, or mineral tailings) are forced against the steel walls with tremendous pressure and velocity, acting like sandpaper and rapidly eroding the metal.
The tiles solve this by presenting a surface far harder than the abrasive particles themselves. Made via powder metallurgy, the sintered tungsten carbide possesses a hardness of 88-93 HRA, making it highly resistant to cutting and gouging. This protection directly maintains the critical internal geometry of the centrifuge (the "beach" angle and cylinder diameter), ensuring separation efficiency remains consistent over thousands of operating hours. Without them, the steel bowl would wear thin, leading to imbalance, vibration, catastrophic failure, and the exorbitant cost of replacing the entire bowl assembly.
