Tungsten Carbide Wear Parts for Centrifuges
Centrifuges are built to separate solids from liquids at high rotational speed, but the same process that makes them effective also creates intense wear. In abrasive service, components inside the bowl, conveyor, feed zone, and solids-discharge area can lose material quickly. Langsun Carbide manufactures tungsten carbide wear parts for centrifuges to help protect these high-wear zones, preserve critical geometry, and support longer, more stable operating cycles.
