Why Dust Control. After dust is formed, control systems are used to reduce, capture and drop dust fines from the air. A well-designed dust-control system can protect workers and often provide other benefits, such as: Preventing or reducing risk of dust explosion or fire. Increasing visibility and reducing probability of accidents.

Dust emission from crushing of hard rock aggregates

Mar 01, 2019 Dust concentrations during crushing were measured at varying distances with time intervals of five seconds. The variation in dust concentration was high within all the measured distances, ranging from 10 to 200 m. Crushing produces mainly coarse (TSP and PM 10) dust particles, which settle near the dust source.
