Wind Fence

Tailings Ponds can be a significant source of respirable dust that can pose a health hazard to nearby communities. A large majority of the dust particles are typically under 10 microns in size, in some cases as much as 80% . Dust of less than 10 microns is capable of penetrating into the lungs contributing to respirable health issues.pond-dust-googleDust from trailings pond

Dust Solutions DustTamer Wind Fences can play an important role in preventing dust generation and dust leaving the pond site. These applications can be complex in nature and may require several methods of wind fence deployment. This includes fixed fences, multiple fences and portable wind screen panels. Wind fences are sometimes combined with other control measure such as water sprays. Reduction of wind over the wetted area can slow the evaporation process thus extending time between water applications and reducing water usage and possible run-off.

DustTamer Wind Screen Fabric is usually attached to free standing column supports (by others), existing structures or on steel frame panels that DSI can fabricate to your needs.

Free Standing Wind Fence column materials are usually selected based on site specific conditions, available materials and engineering requirements. Typical materials include, wood poles, wide flange steel beams, HSS (Hollow Structural Sections) and steel pipe.

On Existing Structures such as Transfer Towers it is used in place of solid siding on a building and the existing column supports can often be used with little or no modification. Other times, attachment hardware is custom designed and may include prefabricated panels for specific areas where pipe or conduit must penetrate the screen.

Steel Frames can be fabricated to cover a transfer point similar to a cage or awning, as a wind guard panel. Many times the screen is used in conjunction with Dry Fog to help control air movement and contain the fog with the dust long enough for dust agglomeration to occur, like at a dump pocket.

DSI can provide Design Wind Pressure Data for our fabrics to be used for the engineering of fence structures on request.

D.S.I. DustTamer Wind Screen Systems are used in a variety of applications as a measure to lower ambient air velocities thus reducing the amount of airborne particulate from many types of sources. These sources typically include material stockpiles, stack-out conveyors, truck, rail or loader dump pockets, vibrating screens, grizzlies, conveyor transfer points and load out silos.

Many times Wind Screen Systems are used in conjunction with D.S.I. Dry Fog Systems to help the agglomeration and settling of dust by controlling and containing the dust/fog mixture at a fog application point.

Wind Screen Systems work better than a solid structure in the above applications, because of the fabrics specially designed porosity. DustTamer is available in two porosity's (30% & 50%) that allows a percentage of the ambient air to bleed through the fabric helping to equalize the pressure differential from one side of the fabric to the other. This reduces the velocity of the wind over the area of typical dust generation.


Several factors must be considered when designing a DustTamer Wind Fence System. These factors fall into three main categories:

  1. Wind Direction(s) that is creating a dust problem.
  2. Existing site conditions including equipment traffic patterns, other structures (including underground) and topography of terrain.
  3. Engineering factors that could include results of Computational Fluid Dynamics (computer modeling), wind load, seismic conditions, soil type and selection of column supports.

D.S.I. can assist in the evaluation of these factors.  If engineering of the structure is required, DSI may be able to provide those services, typically in conjunction with engineers that provide certified drawings for your local. To help us in our evaluation we have provided a pdf Data Collection Guide for Wind Fence that can be used in conjunction with our RFQ Form.

DustTamer Wind Fence/Screen Systems, can be a highly effective measure to help control fugitive dust. It is a cost effective alternative to buildings and other solid structures.

Installation Tools

The following are the basic installation tools that are required. Additional equipment and quantities of equipment and tools such as man lifts, electrical generators, and extension cords may be required depending on the size of the fence or screen, and site conditions.

  1. A spring scale 0-500 lb. range to measure fabric tension.
  2. A come-a-long, to tension the fabric.
  3. A power driver with hex nut driver.
  4. A tensioning tool to attach the come-a-long and scale to the end of the fabric.
