dust suppression for small coal screening operation

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.

The particle size of the dust is a property that influences the explosibility of the dust cloud. Powders include pellets (greater than about 2 mm), granules (between 2 and 0.4 mm) and dust particles (less than about 0.4 mm). The finer the particles the greater the surface area per unit mass, and thus the more explosive a given dust is likely to be.
