In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

that is very common to confuse a mineral crystal for a cleavage fragment. Mineral cleavage is reproducible when a mineral is broken, but if you break the smooth faces of a crystal then you destroy the crystal. The smooth faces of a crystal are not reproducible when the crystal is broken. Several crystal shapes that can be found in some minerals.
