Atomic Packing factor for SC BCC FCC and HCP. In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is dimensionless and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres.

Because the lattice points on the corners are defined with respect to the center of each of the spheres, we know that each of the corner spheres will contribute frac{1}{8} of their total volume to the occupied volume of the unit cell. In addition, the sphere at the center will contribute its entire volume to the occupied volume.

J B = the fraction of the mill volume occupied by the bulk ball charge. If the masses of the rocks and balls were M R and M B respectively and V M the internal volume of the mill, then the fractional volume of mill occupied by the bulk rock and grinding media will be () J R = M R / ρ S V M × 1 1 − φ () J B = M B / ρ B V M × 1 1 − φ
Random close packing (RCP) is an empirical parameter used to characterize the maximum volume fraction of solid objects obtained when they are packed randomly. For example, when a solid container is filled with grain, shaking the container will reduce the volume taken up by the objects, thus allowing more grain to be added to the other words, shaking increases the density of packed ...
