Dry bulk shipping and global trade is vital to many industries; the estimated 500 billion tonnes of dry bulk material support everything from steelmaking to the beer you crack open at the end of the week.
Loading and discharging bulk cargo or dry bulk from vessels is a specialized task often done by stevedoring companies and designated terminals.
Most dry bulk materials are dusty and therefore likely sources of wind-borne dust emissions. When large volumes of material are being discharged from vessels and allowed to freefall in open air conditions, even at a distance of 75 cm or less, the increase of speed of the material will displace air and create air turbulence. Causing dust particles to become airborne, therefore dust nuisance can occur even during calm weather conditions.
When the material travels on site, either manually or via the conveyor belts from the hopper/feeder to the stacker and ultimately when building the stockpiles, it becomes vulnerable to mass loss by wind; especially during long term storage.
