Highly polished YSZ (Yttrium stabilized ZrO2) zirconium oxide jars has the performance of high wear resistance. Its hardness is 60 times the hardness of ordinary steel, highly wear-resistant and resistant to acid and solvents. The grinding jars are extensively applied on in the fields of Paint, Ink,Coating, Geology, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection and so on. Each jar set includes grinding jar, jar lid, rubber sealing gasket and different sizes of mixed zirconium oxide grinding balls.

Choice of Grinding Jars&Grinding Ball
In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen.
