Crushing, milling and screening operations can be major sources of dust due to major reductions in grain size during comminution and segregation processes. Estimates of dust emissions from common mineral processes demonstrate that dust emissions increase as the size of the material processed decreases (US EPA 2004 ).

The main sources of dust generation are crushers, screens, dedusters and transfer points between handling units. Other sources are storage piles and railway wagons used for loading or transfer. Dust control has a dual function of cleaning the air in order to avoid health hazards and recovery of coal.
