Pulverization 1: Definition and purpose | THINKY USA
In a narrow sense "grinding" is used (also referred to as friction grinding in mining). "Grinding" refers to pulverization in the area of finer particle size (crushing of fine particles) and may be distinguished from crushing. Besides these, "milling", etc. are also used. Thinky Corporation uses "pulverization".

Superfine powder with median particle diameter of 25.57 μm was produced through grinding. It was evident from the environmental scanning electron microscopy analysis that during superfine grinding, mechanical shear stress played its crucial role in breakdown of the SFP and causes increases in surface area owing to reduction of particle sizes.
