ZTA ceramic wear liner
Based on the practical testing on
some giant mines in Australia.ZTA liner is proved to be nearly 2.5 times higher than Alumina liners. Such excellent anti-wear ability makes ZTA the ideal material to protect the equipment wherever suffering the extreme wear&impact particularly in mining ,power plants, cement plants, steel mill , ports.By using the ZTA, equipment life time is largely extended and the costly downtime for maintenance is avoid.
