Mill wheels 'grind' as does a pestle in a pestle and mortar. The definitions of "pulverise" that you give include both "grind" and "pound". This shows that "grinding" and "pounding" are different processes which can contribute to the process of "pulverising" something so "pulverise" is a more general term incorporating both of the others.
