After initial crushing and screening, industrial sand and gravel are washed to remove unwanted dust and debris and are then screened and classified again. The sand (now containing 25 to 30 percent moisture) or gravel then goes to an attrition scrubbing system that removes surface stains from the material by rubbing in an agitated, high-density ...

The dust management system treats the material from the top and bottom during discharge. Mark Strebel explains how a dust control strategy in a limestone mine is preventing fugitive dust emissions.

Sometimes classified as Washing Equipment, wet dust suppression systems are typically integrated on standalone conveyors or newer machinery that involves conveyor belts and screens, (like crushers that include built-in belts and/or screening capabilities). This equipment tends to generate the most dust in a variety of aggregate production and ...

Dust causes electrical switches to malfunction because it stops the contacts from correctly seating. Electrical systems under positive air pressure don't permit dust to penetrate the control system. In control panels with a correctly maintained positive pressure system, filters remove dust from air that is being pumped into the cabinets.

Our lime handling systems incorporate dust collection systems, which may include cyclones, bag filters, or other appropriate technologies, to capture and contain the dust generated during conveying, crushing, and …

Road wetting is effective, but continual maintenance must be practiced. Use traffic control as a dust control technique: Max exposure occurs within 4–15 seconds behind a haul truck. Require trucks to maintain more than 20 seconds of separation. May result in a 40%–50% reduction in respirable dust exposure to the following truck.

The intent is to have the droplets collide and attach themselves to the dust particles, causing them to fall from the air. In these cases, droplets in the range of 10 to 50 microns have been shown to be most effective [Bartell and Jett 2005]. Uniformity of wetting is also a very important issue for an effective system.
