Steel windbreak and dust suppression wall is an advanced technology to solve the problem of dust pollution in the open yard of bulk material. It is widely used in high-speed rail, high-speed railway, port and other traffic areas, extended to dust pollution control of thermal power plants, coal mines, coking, steel, coal washing, cement plants, and other business fields which have coal yard and material yard. Using the principle of aerodynamic, the source of the dust, wind, which is effectively controlled. So that, it can reduce the dust arousing and carrying capacity of wind and achieve the effect of dust suppression. Dust suppression rate can be much more than 80%. At present, it has been one major dust pollution control technology being applied.
