Stone dust is also known as rock dust or quarry dust, and some products just have the brand name. The stone dust is collected using a screen that keeps the larger pieces of crushed stone above the screen while allowing the rock dust to fall through. This process is the reason why stone dust is often called quarry screenings.

Nov 11, 2019 Crushed stone If you hear the generic crushed stone term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
Actually, stone dust is more difficult to compact fully than crusher run, the aggregate base material mentioned earlier. Any base material, if not fully compacted, is likely to settle. Most contractors and do-it-yourselfers, who have worked with both stone dust and crusher run, would agree that crusher run is the winner for compacting.
Jul 26, 2021 Crushed stone typically has a residue of stone dust and is commonly used as a base to absorb heavy impact, notably on concrete and paving projects, foundations, and driveways. Stone Dust Stone dust has the fine consistency of sand that is created in the crushing process.
