These balls are made from the highest calcination grade of alumina, which gives them
excellent mechanical properties while also providing them with high chemical stability.
The XIETA®-80 ball is part of the medium-density ball group. This type of ball provides more
efficient grinding than BTS®-75 balls. They are recommended for grinding clays, pastes, etc.,
and all raw materials that are not recommended for grinding with low-density balls, such as
calcium carbonate, talc, and magnesium carbonate.
