The grinding balls corrosion rate may increase by several orders if the temperature rises by 100 degrees. The grouts very intensively destroy the grinding media steel at low pH values (0-7), i.e. at hydrogen ions high concentration. The corrosion process of steel slow down at pH values greater than 9.
