At concrete crushing facilities, dust is generated at multiple points. Front end loaders, hoppers, and conveyor discharge points all bring dust when operational. Front end loaders transfer the incoming demolition materials to the hopper. Picking up these rocks creates dust as they are disturbed and dumped into the hopper.

Dust collection in the crushing plant is accomplished by two wet dust collectors with a total of 66,000 CFM. The dust collectors exhaust air is discharged to the upper ventilation system of the mine through an 800 ft. vertical raise and then through mine fans to the surface. The screening area exhaust system has exhaust hoods with 1500 CFM each

Road dust, crushing plants, tailing dams, and manufacturing plants all contribute to the dust emissions on a mine site. Managing airborne dust can be labour intensive as dust levels need to be measured continuously and if the limits are breached, production must stop until remedial action is taken.
