Blasting also results in large amounts of dust generation – and is one of the hardest operations to manage. The blasted rock is fed into crusher bin. Bigger rocks are also fragmented with a hydraulic impact hammer before crushing. Drilling and blasting cause dust emissions as does crushing, sieving, and conveying.
