    Dust control strategy using water sprays

     · For dust suppression, drops between 20 and 200 µm are typically required as airborne dust particles are usually in this size range. To produce this very small drop size, a higher degree of atomisation is required. Atomisation is achieved by pumping water through nozzles at high pressure or by using a combination of compressed air and water pumped at lower pressure to produce very small .

    What is Stone Dust and Why Would You Get It?

    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. Crushed stones are graded by number according to the size of the ...
