Description of KERAVAT sintered alumina ceramics
Engineering ceramics sintered Al₂O₃ with high wear resistance in erosive wear conditions. The shape and the thickness of the ceramic parts can be adapted to the application. Because of the very high wear resistance and weight reduction is possible because of the low density.
KERAVAT sintered ceramics are the best choice to line tubes and bends with adapted ceramic segments.
Applications of KERAVAT sintered alumina ceramics
Cyclones, chutes, mixers, filters, scrapers, centrifuges, bunkers, granulators, rotary valves, tubes, pumps, reddler, chain bottoms, valves, nozzles, plunjers, conveyor screws, ….
Fixing of the KERAVAT ceramic parts
The ceramic tiles are fixed with a flexibel 2-component adhesive for temperatures up to 150°C.
For temperatures up to 250°C we recommend a special high temperature adhesive.
For applications at higher temperatures above 250°, a mechanical fixing is required.
