What is Stone Dust and Why Would You Get It?

May 27, 2019  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.

Effective Dust-Suppression in Quarries Agg-Net

In limestone quarries, where the silica content is low, exposure to RCS may well be below the WEL. Nevertheless, such quarries still need to ensure that the amount of inhalable dust does not exceed 10mg/m3 over an 8-hour period and exposure to respirable dust should not exceed 4mg/m3.

(PDF) Influence of dust from a limestone quarry on ...

Since limestone quarry dust is highly alkaline, the caustic effect of the dust on the leaf surface may also be a factor. The reduced rate of photosynthesis and reduced stomatal conductance would be consistent with the blockage of leaf stomata by dust particles. Reduced photosynthesis and blocked stomata, amongst other effects, have been ...

The Importance of Effective Dust Suppression in Quarries ...

May 25, 2016  The Workplace Exposure Limit (WEL) applies only to the respirable fraction of the silica dust. This means the portion of dust that reaches the deepest parts of the lungs – which is said to be around 10-20% of the total inhalable dust. In industries such as limestone, where silica content is low, exposure levels to RCS may well be below the WEL.
