Pulverization 1: Definition and purpose
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".
