How Alumina Balls Are Created

Inert alumina balls are used in a wide variety of industries. They are resistant to high temperatures and don’t cause pollution. You can see the process of making these balls in the video.

The process begins with high-purity alumina powder. A semi-isostatic press is used to shape them into balls. The powder is placed into the molds by a machine. Then, liquid is used to create equal pressure on all sides. Then, the powder is pressed to create the ball shape. These balls are smooth and uniform in shape and appearance. However, this is only the first part of the process.

Next, they are placed into a tunnel kiln. The kiln has a temperature of 1650 degrees Celsius. This allows the balls to cure and gives them some of their unique properties.

These aluminum balls have high strength, high hardness, high abrasion resistance, high specific gravity, small volume, high-temperature resistance, and corrosion resistance. They can also tolerate extreme temperature changes. The balls have a wide variety of uses. They are often used to make different types of ceramics, enamel, and glass. They are also used in chemical plants. They can also be used for finishing and deep processing of hard materials.
