HITO®-75BTS alumina balls are balls made from high-purity bauxites, which contain high amounts of Gibbsite, ensuring an alumina content of 75%. This alumina content gives these balls mechanical properties and wear resistance far superior to those typically found in bauxite-based balls.

HITO®-75BTS balls are the type of grinding media being used as a natural substitute for silica balls, improving their performance due to the high quality and purity of the raw materials used for their manufacture, their high sphericity (due to isostatic pressing), and their high density, which give them excellent properties as a grinding media.

This type of ball is recommended for grinding all types of soft raw materials, offering the following advantages over silica pellets:

• Reduction in grinding times.
• Reduction in particle size dispersion after grinding.
• Increased production.
• Reduction in energy consumption.
