Rock Dust – Rock dust collection systems are used at quarries and mining operations. They are heavy duty equipment designed to operate in harsh and hazardous conditions. Their main function is to control ambient dust that is a part of the mining process such that it does not spread from the area of the operation.


Combustible dust is our specialty and we offer a safer alternative to conventional dust "collection" techniques. The Technology Behind our System. Englo dust extractors use energy generated by the fan to encapsulate the dust particles into atomized water. This mixing requires an aggressive energy transfer in a small space.


A consultant hired by the quarry's applicant suggests three methods to offset the amount of silica dioxide in the air, according to Lane County meeting materials: using dust collection systems on rock drills, delaying blasting when winds go above 25 miles per hour and spraying water on aggregate trucks leaving the quarry.


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.

For example, when using vehicle-mounted drilling rigs for rock and concrete, employers can be in compliance in one of two ways: Use a dust-collection system with a close-capture hood or shroud around the drill bit, with a low-flow water spray to wet the dust at the discharge point from the dust collector; or have employees operate from within ...


Such dust suppression techniques are commonplace and hence the relatively high potential for dust emissions from this source is rarely if ever realised. Detonation of the explosives results in either ground heave in the case of opencast coal site blasting or the formation of a rock pile in the case of typical quarry blasting.
