Description
Balls for crushing alumina. It is created by mixing, pulverizing, grinding, molding, drying, and sintering, and the raw materials used include bauxite, roller powder, alumina, and high-temperature calcined alpha alumina powder. It is primarily used as grinding media and is extensively employed. Depending on the alumina concentration, it may also be separated into medium aluminum balls, medium high aluminum balls, and high aluminum balls.
Features
Low wear, high hardness, impact resistance, resistance to corrosion, economy, and practicality are all characteristics of aluminum oxide grinding balls.
Alumina balls may significantly boost grinding efficiency, decrease grinding time, save energy, and lower costs while also efficiently increasing the ball mill's effective volume, which increases the quantity of grinding material added.
Manufacture method
Agglomeration is used to create alumina ceramic balls and is a reference to the semi-dry and wet shaping procedure used to create dumplings. It is created by repeatedly pressing dry powder on the outside of the "wet core."
Alumina ball dry isostatic pressing
Application
Ultra fine grinding ceramic grinding media are extensively employed in the production of luminous materials, semiconductor electronic packaging, lithium batteries, catalysts, protective coatings, grinding and polishing, ceramic materials, cement powder, etc. They have gained a wide variety of markets in the grinding sector.
