The storage of materials is usually carried out by a mobile bucket loader moving a full bucket load at any one time in various directions.
In such conditions the most practical method of dust suppression is to mount nozzles high in the roof area of the storage facility. Such nozzles produce a nominal 5 micron droplet, which evaporates into the surrounding air without falling to floor level and causing wetting of operating surfaces.
Flow is minimal at only 8 litres/hour per nozzle – ie 2.5ml per second (1/2 teaspoon) which is almost negligible. Due to the low flow and micro fine droplets, the fog can be deemed “dry”. This in turn facilitates the nozzles to remain constantly on throughout the working process, as the cost of running the system is extremely cost effective.
