Description
High alumina balls are distinguished by their high alumina content and are utilized extensively in several sectors as a result of their exceptional benefits.
In general, we classified balls with alumina contents of 60%–65% as medium–aluminum balls, 75%–80% as medium–high–aluminum balls, and beyond 90% as high–aluminum balls. They are further split into 90 porcelain, 92 porcelain, 95 porcelain, and 99 porcelain high alumina balls. 99 porcelain is seldom made in large quantities by major manufacturers due to its extraordinarily high manufacturing costs; instead, it is often made by hand in a few unique ceramic companies.
Features
(1) High purity, high alumina concentration (92%–95%), and won't contaminate the grinding materials Alumina is inert, thus it doesn't really react with acids and bases and won't chemically interact with ground material;
(2) The grinding ball made of high-aluminum alloy has a high hardness, strong wear resistance, and a long lifespan.
(3) High aluminum balls are corrosion-resistant and have a high mechanical strength. Alumina ceramics have a Mohs hardness of 9, which is just one grade lower than that of diamond (which has a Mohs hardness of 10). Alumina is inert, does not react with acid or alkali, prevents steel linings from corroding, and is not resistant to corrosion by sodium hydroxide, concentrated sulfuric acid, or concentrated nitric acid;
Application
Because of Cheap High Density Alumina Grinding Ball exceptional qualities, high-alumina grinding balls are frequently used in companies making ceramics, enamel, glass, chemicals, and other materials to complete and thoroughly process thick and difficult materials. One of them is 92-inch-high metal grinding balls. primarily utilized in the manufacture of fine powder, chemical packing, and other industries. suitable for environments with high temperatures, high pressures, and corrosive materials. Due to its low silicon and impurity concentration, it is also appropriate for catalytic supports.
