  • Studies of Grinding Media Corrosion from Galvanic ...

    Corrosion rates of eight alloys commonly used in grinding media were tested in synthetic mill water using an ultrasonic grinding device especially designed for this work. Electrochemical measurements showed variations in corrosion rates for these alloys between 9.8 Mpy for medium-carbon steels and 0.14 Mpy for high-chromium white irons.

    The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process. Is there a risk of abrasion, corrosion or impact? And what are the factors influencing these?

    couple between the grinding media and the sulphide mineral(s) exists, which increases the corrosion rate of the forged steel media. The corrosion products of the grinding media, iron oxy-hydroxide species, invariably precipitate on to the surfaces of the sulphide minerals, thereby affecting their floatability (Johnson, 2002).

    This study has been done to determine the galvanic interaction between five types of grinding media (mild steel, cast iron, 10% chromium, 20% chromium, and ceramic media) and galena, in situ of the mill. The ceramic media has a significantly not galvanic interaction with galena and high chromium media has a significantly weaker galvanic interaction with galena, and produces a very much lower ...
