Semaphore reduces dust in bulk handling

The bumper grain harvest in South Australia has led to record throughput for Semaphore Containers in South Australia. With more loading activities there is more dust being generated. Being a proactive company Semaphore engaged Blue Water Misting to reduce dust in their operations.

Blue Water Misting (BWM) analyzed the site in consultation with customer identifying the sources of dust. They thenn purpose designed a system the to help then reduce dust in the areas of: Truck receivals from the farm to silo; Truck load out to the ship loader; Container stuffing; Hopper loading

“We engaged BWM to install dry fog dust suppression at several points in our operation. The result has been a significant reduction in dust emissions,” said Michael Raidis, Manager Sempahore Containers

Blue Water Misting worked with the client to determine the sources of dust and prepare a solution for the fugitive dust emissions. They placed a large power pack centrally on site then used specialist nozzles to produce a DRY FOG that adds less than 0.25% moisture to product.

BWM is designed in Australia and marketed worldwide for use in dust suppression at ports & bulk handling facilities. They employ several techniques to reduce dust they include dry fog misting, extraction and one way barriers –Flex Flap

The company uses a patented system of product specific nozzles to control the spray droplet size and distribution. This control allows the droplets to attach to commodity specific particle sizes and drop them out of the airborne environment.

BWM has developed ore specific nozzles for coal, iron ore, mineral sands, copper concentrates and others and provides dust specific a suppression system that work more efficiently than a normal dust suppression system.
