The bulk density of a new rod charge is about 6.25 t/m 3. With time due to wear the bulk density drops. The larger the mill diameter the greater is the lowering of the bulk density. For example, the bulk density of worn rods after a specific time of grinding would be 5.8 t/m 3 for a 0.91 m diameter mill.
