CERAMIC CYLINDRICAL PINS SILICON NITRIDE(SI3N4) OR ROLLERS ZIRCONIUM OXIDE(ZRO2)
refractory ceramic material rollers, they provide excellent corrosion, wear and heat resistance. they improve their hardness when they are subjected to collisions. yttrium doped zirconia oxide, they provide the best properties between ceramic materials in grinding and milling applications. we have a roller made out of this ceramics. this high-strength material exhibits excellent wear and corrosion properties. the material can also be for added strength and edge retention. zirconia exhibits a very low coefficient of friction and is available in mgo or yttria stabilized grades.
