Protection Against Wear

All wear-prone areas of the centrifuge — feed zone, solids discharge, bowl and scroll are protected by hard surfacing. The type of material chosen are to combat the severity of the wear. While composite hard surfacing material like stellite are satisfactory for low and medium abrasive duties, the life of the scroll may be as low as 1000 hours on more arduous materials. It was for such applications the Pennwalt developed a protection system using sintered tungsten carbide tiles.

A major advantage of the Pennwalt system of wear protection is that should any tiles become damaged, up to 20 of them can be replaced, in the need for rebalancing.

The Pennwalt tungsten carbide tiling system has enabled Decanter centrifuges to operate trouble-free on abrasive duties which had not previously been possible. Sintered tungsten carbide is up to 50 times more resistant to wear than flame applied hard facing material. Of greater significance is the comparison with most alumina ceramics which have a low abrasion resistance rating.

Replacement Parts for Decanters
