Product Description

The main characteristics of aluminum porcelain ball is high hardness,the hardness of the aluminum ceramic ball has reached the Mohs hardness level of 9 or more, which can easily resist various wear and impact.strong corrosion resistance: aluminum ceramic ball has good chemical stability, can be used in acid, alkali and other corrosive media, not easy to be damaged.strong wear resistance: The wear resistance of aluminum porcelain ball is very strong, can be used for a long time in the environment of high-speed friction, and is not easy to wear.

Product Application

Medium alumina ceramic ball is high hardness, high density, wear resistance and other characteristics, often used in grinding machines, ball mills and other abrasive equipment, can effectively grind a variety of ores and other materials.aluminum porcelain balls can withstand the corrosion of various chemical media, so they are also widely used in the chemical industry, such as for the production of alumina, silicon dioxide, titanium dioxide and other products.the hardness and density of aluminum ceramic balls are very high, and can be used for grinding and processing of ceramic materials.
