Extracting the rock. In an operational quarry, the process starts off by breaking off large chunks of rock from the quarry walls, usually through controlled blasting. The rock is then moved using loaders and trucks to a primary crusher. GRT offers the following dust suppression solutions during the extraction process: GRT 12X – blast …

Once the pavers have been installed on top of the stone dust bed, use a vibrating plate to compact the bed and pavers even more. However, note that stone dust doesn't compact well due to its powdery texture. It can cause shifting of the pavers later on which is why it's not really recommended to use this for your installation bed.

Sand has a fine texture so will usually create a smooth surface. With stone dust you have options in terms of the texture, so you can achieve a smoother surface, or opt for a more rough one if desired. Generally, stone dust is cheaper than sand, so you can save money by going with stone dust. The bigger the project, the more you will save.
