Estimation of dust emissions from stone crushing process is mainly based on data and models proposed by the US-EPA (uses AP42: Compilation of air Pollutant Emission Factor). An emission factor is a representative value that relates the quantity of a pollutant released to the atmosphere with the industrial activity producing the pollutant.

The fines in the dust generated increases with subsequent stages of crushing i.e., more fines are generated in secondary crusher as compared to primary crusher. The dust is also generated during handling of stones, especially at the point where the stones fall through a height from places like one belt to another or from belt to hopper or stock
