The table also includes the Bond Work Index, which is discussed in the next section. An initial size reduction from material several centimetres in diameter down to one centimetre, or so, is often termed primary crushing. This may be followed by further size reduction, secondary crushing, and then pulverising, or fine grinding. The term micronising
The Bond Index conforming rod charge consists of 6 rods of 1.25 diameter and 21 length. 2 rods of 1.75 diameter and 21 length.
