Effective Dust-Suppression in Quarries Agg-Net

First published in the December 2017 issue of Quarry Management as The Dust Factor. Brigitte Pennington from Conflow looks at the importance of effective dust-suppression systems in quarries. One of the greatest threats to health and safety in quarries is the dust known as respirable crystalline silica (RCS).

Diatomaceous earth Wikipedia

Diatomaceous earth (/ ˌ d aɪ. ə t ə ˌ m eɪ ʃ ə s ˈ ɜːr θ /, DE), diatomite or kieselgur/kieselguhr is a naturally occurring, soft, siliceous sedimentary rock that has been crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 μm to more than 1 mm, but typically 10 to 200 μm. Depending on the granularity, this powder can have an abrasive

Assessment of Distribution and Composition of Quarry Mine

Chemical analyses of dust were done to check on the toxicity of dust from the quarry, so as to predict its pos-sible impacts on human health and the environment. A Casella dust sampler and a GPS were used to collect dust onto the filters and to mark the sampling points respec-tively [4]. 3. Results
