Applications:
Zirconia ceramic ball is mainly used as valve ball, full ceramic bearing, measuring ball, track ball, fine grinding ball, can be used for high temperature, corrosion resistance, insulation, magnetic, no lubrication and other occasions, is the ideal material to replace steel ball under corrosion occasions.
As a valve ball, zirconia ceramic balls have been successfully used in high pressure homogenizer, diaphragm pumps, metering pumps, oil field sucker rod pumps, high pressure spray guns and other equipment. Zirconia ceramic balls can also be used as walking ball and ball for skin care bottles/cosmetics packaging bottles.
