Deadly Dust. Silica dust is very fine, much smaller than a tiny grain of sand found on a beach. This is what makes it so easy to inhale. If you look at the full stop at the end of the previous sentence, that is around 200-300 micrometres in diameter. Whereas the respirable crystalline silica particle is only 5 micrometres in size.

The potential of crusher dust. Crusher dust serves as an ideal fill material for the creation of pathways and driveways, and as a base layer for artificial turf. Properly laid, it enhances drainage and minimises waterlogging, boosting surface longevity. Its compacted structure acts as a natural weed suppressant, making it suitable for weed ...

Typically road base comprises a mixture of blue or grey rock fragments around 20 mm in size with smaller rock particles and dust (fines). Crusher dust is produced when recycled concrete or rocks are crushed. It is finer than road base comprising particles that are 5 mm or smaller in size mixed with fine particles, such as soft sand.
