The dust control will suck up the contaminants that collect on conveyor belts, while the dust suppressant helps stop dust particles from spreading as they move through other parts of a quarry or stone breaker.
Crusher Dust
Product Description. Crusher dust, also known as blue metal dust or rock dust, is a byproduct of crushing rocks in quarries. When rocks are crushed, tiny particles and dust are left behind. Rather than being discarded as waste, this dust is collected and processed, turning it into a valuable material for various construction applications.
