ALUMINA BALLS
MEDIUM DENSITY. XIETA®–75 BTS

Xieta® 75BTS alumina balls are manufactured from high-purity bauxites that contain elevated amounts of Gibbsite, ensuring alumina content of 75%.
This alumina content provides the balls with mechanical properties and wear resistance far superior to those of typical bauxite-based balls.

Xieta® 75BTS balls are a type of grinding media increasingly used as a natural substitute for silica balls, offering improved performance due to the high quality and purity of the raw materials used in their production, their high sphericity (thanks to isostatic pressing), and their high density, which grants them excellent properties as grinding media.

These balls are recommended for grinding all types of soft raw materials, offering the following advantages over silica balls:

  1. Reduced grinding times.

  2. Reduced particle size dispersion after grinding.

  3. Increased production output.

  4. Lower energy consumption.
