2019-3-1 Dust constitutes one of the major environmental concerns near many aggregate quarries, with crushing often being the most significant source. In this study, dust emissions and dispersion measurements were conducted under real operating conditions at
Read MoreBoth ambient dust concentration and occupational exposure level exceeded Indian National Standards at most of the locations. Mathematical models viz., FDM, ISCST3 and AERMOD were employed for prediction of dust emission from stone crushers on the surrounding areas. The impact zone for measured concentration varied 211–1350 m with a mean of 784 m.

A cluster of 72 stone crushing units located at Trisoolam in Chennai is a source of high levels of dust generation in the vicinity of the crushers and in the communities surrounding them. An ambient air quality monitoring network was designed and operated over 3 months (June–August, 2006 ...

Primary crushers will normally reduce stone to 1 - 3 inches in size. Secondary crushers are normally used to reduce stone to sizes below one inch. These are usually cone crushers or high-speed, flat-angle gyratory machines.
