    Commentary on the apparatus of the Bond rod mill

    The specification for the apparatus to determining a “Bond” rod mill work index is first described in Bond & Maxton (1943). It states that the apparatus is a tumbling rod mill to be operated in a locked cycle test at a fixed circulating load. The geometry of the grinding chamber is described as: • mill inside diameter of 12 inches
