Ports and Bulk Storage

< >

ADSTM Dry Fog based dust control is rapidly gaining acceptance in ports and bulk storage facilities. Recent installations include coal, sulfur, iron ore, and grain facilities in countries from Chile to Australia to Madagascar to India.

One very interesting integration of a passive and an active technology is what we have created on the Unloading Hopper at Ports facilities, putting together a windfence and the ADSTM Dry fog from the Raring Corp we can offer a pretty unique way to control the dust at these specific points. We have had successfully use this integration in many applications and in different industries. The most important requirement for ADSTM Dry Fog, to successfully work controlling the dust, is the need of containment. Adding a  windfence is a good way to add the containment feature to the dust control system, maintaining the fog and dust on the controlled boundaries which help give the fog the retention time needed for doing its job. Specifically, in ports we recommend our clients to consider both ADSTM Dry Fog and windfence on the unloading hoppers, which we have had implemented in several ports in different parts of the world, giving a successful solution for controlling the dust in a challenging and always difficult application. The hoppers are always exposed to wind gusts from different directions and the operation limits the amount of windfence to be installed, nevertheless the integration of these two technologies seems to be a good fit to our clients.

Ship loaders are a bit more difficult and each one presents its own challenge.  Containment becomes more difficult and most of the time an operational modification is needed to help minimize the amount of dust generated. What happen when a ship is being load with bulk material is that the material falls free down into the ship bunker and when it hits the bottom, the dust starts coming out from the sides of the pile that is being build.  The wind does not help at all and it can get into the ship bunker blowing the dust out of it. On this specific application we totally recommend considering a telescopic chute integrated with a TRC ADSTM Dry Fog spray ring, on the bottom end of the chute, providing the dust control system the containment required and the active dust control system (Fog). The telescopic chute will help to load the bunker from the top of the pile, al the time, and the spray ring will generate enough fog to fill the bunker with a dense cloud of fog to keep the dust inside of the ship bunker. When dust is generated, and the spray ring is fogging, dust gets together with fog, the dust particles become heavier and they settle down into the bunker.

Where to Use Fog:

ADSTM is the right choice for

  • Unloading Hoppers
  • Loading and unloading Barges or Boats
  • Conveyor transfers
  • Bins and Silos
  • Truck and rail loading and unloading
  • stackers and reclaimers

Fog is often used in conjunction with passive dust control technologies such as wind fences, conveyor hats, Stilling Sheds and engineered chutes.

Where To Use Water or Water with Chemical:

  • Open stockpiles
  • Moisture conditioning for storage or transporting
