Dry bulk shipping and global logistics are of vital importance to many industries
The loading/unloading of (dry) bulk materials such as coal and ores from/in seagoing vessels and inland barges, trucks and freight trains or the movement of bulk batches at storage sites is often a rather "dusty" affair. Loose dust particles escape by air movement through the air and this causes dust formation and thus dust nuisance for your employees and the environment, even when the weather is calm. In addition, valuable material is lost and you simply feel this in your wallet.
On site, bulk materials are transported to and from the stockpiles using shovels or conveyor belts. These piles of bulk material are then stored on your site for varying lengths of time. Stockpiles are generally highly susceptible to weather conditions such as wind or rain.
Wuvio knows from its own experience that dust suppression using water alone during transport or storage is, unfortunately, not sufficient. Furthermore, water is becoming an increasingly scarce resource. In many places, it is no longer even available in sufficient quantities (for dust suppression), and as a result, its use is also becoming increasingly expensive.
We understand your dust-related challenges better than anyone else and therefore offer you effective, efficient and affordable solutions for reducing dust emissions.
For example, when storing bulk materials, our crust-forming agents are sprayed over the stockpiles like a blanket, forming a thin, durable crust – available in white, green or transparent as required – which significantly reduces the drift and loss of material. Depending on requirements, the lifespan of this crust is 2 to 52 weeks, or longer if necessary.
Experience shows that dust challenges also occur at drop points on the belts or when handling the bulk material in the hopper. Here, solutions based on atomization can be employed. Moreover, by adding an additive to the mist, the action of water is much more effective. This is because the additive ensures that the water opens up, as it were, and can therefore hit/bind dust particles.
By using our dust control solutions, water consumption savings of up to 70–80 per cent are achieved initially.
Wuvio offers solutions for reducing dust nuisance and material loss at all stages of dry bulk handling, storage and transhipment:
Freko-Crust or Eco-Crust S (transparent or coloured) create a protective top layer on the stockpiles, ensuring that the stored material is exposed to the wind as little as possible.
Water atomisation and the addition of Freko-Humidifier – an additive that reduces the surface tension of water – prevents dust formation during the handling and transport of bulk materials.
Dry foam, Freko-Foam, is primarily used at drop points or transfer points on conveyor belts or in crushing plants. The foam has a binding effect and thus prevents dust formation.
RDS (Road Dust Solution) is an additive that is mixed with water and is easy to apply using a spray boom and a water tanker.
