Dense-graded aggregate (DGA): Also known as "crusher run" or "road stone," DGA is a mix of crushed stone and stone dust. The stone dust fills the voids between the crushed stone, providing a more stable and compact base. This material is excellent for driveways, as it can withstand heavy loads and provides a smooth, even …

In general, all kinds of concrete crushers would produce plenty of dust when it is crushing the ore materials. The reason why it produces so much dust is that the material through the feeding port is crushed then being sent to the conveyor for the next process, during which a lot of dust with high concentration would diffuse around under …
