Stone Dust: What It Is, Uses, and Where to Buy It
When stones are run through a crushing machine to make crushed stone, stone dust also forms. Its exact composition will depend on what kind of stone ran through the machine, such as granite or limestone. The machine has a screen that traps the larger crushed stone and lets the smaller material (or "screenings") fall through the screen.
