In general, high density grinding media will disperse high viscosity and/or high density millbases faster. In practice it is difficult to allocate ballmills according to the densities of millbases, therefore the general use of steatite balls ( ρ = ) or alumina balls ( ρ = ) will give very satisfactory results.
