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.

Hammermill and impact crushers use a rotating device (hammers) to thrust the ore against the outer walls of the crusher with the intent to break the ore by impaction against the outer surface. Because the ore is impacted at high velocities to induce breakage, high dust generation and liberation rates can occur from these types of crushers.

What is the Crusher Dust?
Crusher dust, also known as blue metal, cracker, or rock dust, is simply the material leftover when making crushed rock. As rocks are run through the crusher, tiny pieces and dust particles are left behind. Instead of being thrown out as waste material, the dust is recycled and becomes a valuable product with many practical applications in both ...
