Ra 0.4 High Precision Zirconia Ceramic Tube For Ball Mill Agitator Roller
Description:
Zirconia ceramic tube is set on the metal mixing shaft of ball mill. The high wear resistance of zirconia ceramic makes the life of metal shaft longer, so zirconia ceramic is a good choice to replace metal parts.
Zirconia has high hardness and wear resistance, so it has a wide range of applications in the field of grinding medium and abrasive tools, such as grinding medium ball mill lining and wear resistant parts of Our country about toughness ceramics in the field of grinding medium accounted for more than half, and the zirconia ball accounted for absolute advantage because zirconia has no magnetic non-conductive non-rust Wear-resistant, so it is widely used in the field of biomedical instruments and tools: such as magnetic materials such as medical scalpel and tape cutting products, artificial bones artificial joints artificial teeth and so on.
