Factory Customized Ceramic Element For Doppler - Zirconia Ceramic Roller – Sanxin Hi-Tech Ceramics

Zirconia Ceramic Roller (ZCR) Zirconia Ceramic Roller (ZCR) is widely applied on the high precision roll machine processing electron and battery instead of alumina ceramic roller and alloy steel roller. It is the key components in the roll machine. ZCR behave high strength and high wear-resistance performance during using in roll machines. The re-polished time of ZCR is more 4 times than alloy steel roller. And service life is more longer than alloy steel roller. ZCR also can be used in crush the large size of non-metal mine and high purity ceramic raw materials.   Material Properties
