As in other operations, crushed stone emission sources may be categorized as either process sources or fugitive dust sources. Process sources include those for which emissions are amenable to capture and subsequent control. Fugitive dust sources generally involve the reentrainment of settled dust by wind or machine movement. Emissions

Controlling dust within crushing operations is critical to keep equipment working effectively and protect the health and safety of workers. As part of Stage 3 of our clients’ site expansion works, a tender was issued for a dust extraction system to manage dust created by two secondary and tertiary cone crushers and three screening plants.

The slusher hoists that feed the coarse ore bin are set up for remote control operations and may occasionally be operated from the central control room; however, the general practice has been to have an operator at the slusher. Dust collection in the crushing plant is accomplished by two wet dust collectors with a total of 66,000 CFM.

Rock crushing plants are inherently dusty operations, and maintaining regulatory compliance for worker safety and environmental protection can be a challenge. A properly designed fog dust suppression system is a foundational component in creating a safe workplace and avoiding fines for allowing fugitive dust to affect the surrounding environment.

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.

Wet dust control methods for crushing operations, involve wetting the process material before crushing, after crushing, or both. This is essentially treating the crushing operation as two transfer points, the feed side and discharge side.

Like most quarries, the company faces some difficult challenges in its attempts to control dust during extraction and processing. Operations such as quarrying, loading, transportation and mobile crushing typically don’t lend themselves to integrated suppression techniques, yet all of these add to the potential for releasing vast amounts of dust.
