Proper Crusher Dust Control: What It Needs. Controlling and minimizing exposure to silica dust requires proper wet dust suppression for rock crushers. Because water has a relatively high surface tension (72 dynes per cm), it alone cannot penetrate crushed material that releases silica dust. Water's hard surface causes its particles to bounce ...

CRUSHING EQUIPMENT USING DUST CONTROL. Concrete crushing facilities are designed to handle rock big and small coming from demolition materials. The large aggregate chunks sent to the facilities see the primary crusher first. These large crushers handle breaking down the bulky rocks into smaller, more manageable sizes.
Wet dust suppression systems have been shown to significantly remove and reduce respirable (breathable) dust, and implementing some of these tools, specifically for crushers and conveyors, can help you reach compliance. Of course, workers will also need to don protective gear within high-dust areas, as well.
What is Crusher Dust (Cracker Dust)? | Ultimate Backyard. Crusher dust is a grey powder, made of finely crushed rock or concrete. As described here, "Crusher dust is the dust that is leftover from concrete recycling when rocks are being crushed. While rocks are going through the crusher, tiny pieces of rock and dust particles are left behind.".
