5 FAQs of High Purity 99 Aluminium Oxid Grinding Ceramic Ball / Alumina Ceramic Ball / Alumina Balls

What exactly are high purity 99 alumina balls?
These are small, round ceramic balls. They are made from aluminum oxide (Al2O3). The purity level is very high, at least 99%. This means almost pure aluminum oxide. They are very hard and very dense. They look white or off-white.

Why pick 99% purity alumina balls?
Higher purity means better performance. It gives the balls extreme hardness. It gives them excellent wear resistance. They last much longer. They resist chemical attack better. Lower purity balls wear down faster. They might contaminate your material. The 99% grade is best for tough jobs.

Where are these alumina balls typically used?
Their main job is grinding and milling. They crush materials inside mills. They work well in ball mills and vibratory mills. They are also used as catalyst supports. They hold active chemicals in reactors. Another common use is as valve balls. They control flow in pipes carrying harsh stuff. They work in pumps too.

How tough and durable are they?
They are extremely hard. They are nearly as hard as diamonds. This makes them resist wear very well. They keep their shape over time. They handle high temperatures easily. They don’t melt or weaken below 1750°C. They resist most acids and alkalis. They don’t react easily. This toughness means less breakage. It means less need for replacements.

What sizes do these alumina balls come in?
They come in many diameters. Common sizes range from very small, like 1mm, up to large sizes like 50mm or even bigger. You pick the size based on your machine. You pick it based on the material you are grinding. You pick it based on the fineness you need. Smaller balls make finer powder. Bigger balls handle coarser grinding. Factories supply many standard sizes. They can often make custom sizes too.
