"Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains, paints, and medicines.
