Dust emission from crushing of hard rock aggregates

Quarries 2 and 6 applied tertiary crushing, relying on three and four crushing units, respectively. No dust prevention techniques, like watering, were applied during the measurements due to risk of freezing. This enabled observation of dust emissions from a Dust measurements were conducted in six aggregate quarries, all located in hard rock formations (Table 1.) Quarries 1, 2, 4, 5 and 6 are open pits producing Dust emission from crushing of hard rock aggregates

Near field modelling of dust emissions caused by drilling

This study compares modelling results to measured concentrations near dust sources in a natural stone quarry and in two aggregate quarries. In the natural stone quarry, the dust source was drilling and in the aggregate quarries, it was crushing.

Natural stone quarries, hereafter stone quarries, produce stone blocks, which are detached from the bedrock by drilling, blasting, sawing or wedging. The aim is to detach stone blocks and the bedrock as intact as possible from the excavation without causing damage [8].

Dust emission from crushing of hard rock aggregates

All processes of aggregate production are potential sources of dust emission. Dust constitutes a major environmental concern in many quarries, with crushing suggested as the most significant source of it (Bada et al., 2013; Petavratzi et al., 2005; Sairanen et al., 2018).
