These balls are made from alumina at its highest calcination rate, which gives them excellent mechanical properties while also providing them with great chemical stability. The HITO®-80 ball is part of the medium-density ball group. This type of ball achieves more efficient grinding than BTC 72 balls. They are recommended for grinding clays, pastes, etc., and all raw materials that we do not recommend grinding with low-density balls, such as calcium carbonate, talc, and magnesium carbonate.
