  • Device for determining the corrosion of the grinding bodies in a rotary mill
    Patent number: 6510729
    Abstract: The mill comprises a cylindrical shell ring (10) revolving about its longitudinal axis and containing a grinding charge comprising grinding bodies made of metal alloy. At least one grinding body (30) identical to those that make up the grinding charge is fixed to an elastomer or rubber pedestal (28), itself fixed to the interior surface of the shell ring. This grinding body (30) is exposed to the conditions inside the mill and is associated with a reference electrode (36) from which it is electrically insulated. This reference electrode (36) is protected from the impact knocks of the charge in the mill but is in electrical contact with the pulp in the mill, the said grinding body (30) and the said electrode (36) being electrically connected to measurement apparatus (18) fixed inside the shell ring of the mill.
