Dust Control or Prevention for Crushing and Screening

Mineral crushing and screening operations can be major sources of airborne dust due to the inherent nature of size reduction and segregation processes. Without adequate solutions, workers' health can be seriously compromised over time. (Relative emission rate ratios of crushing and screening

Analysis on the impact crushing dust generation test

The authors found through tests that the setting of impact crushing program and dust screening program has a non-negligible effect on the dust generation results of samples, especially for coal samples whose moisture contents differ, because broken coal chips will undergo serious water evaporation and loss during the screening process.

Guidance about dusts and other airborne contaminants

Crushing, screening and processing. Dust needs to be effectively controlled at each crusher, mill and grinder, with dust control appliances fitted at the primary crusher feed hopper as well as secondary and tertiary crushers plus screens. Conveyor belt transfer points and stockpile tunnels may also require dust control measures.

However, when used to control dust at tertiary crushing and screening where small product sizes and screen openings are en- countered, problems may arise. The wetted dust tends to blind the openings in fine screens. In agricultural limestone where very fine material is re- quired in a dry state, the addition of water is not practical.
