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 port, thermal power plants, coal mines, coking, steel, coal washing, cement plants, and other business fields which have coal yard or raw material yard. Using the principle of aerodynamic, the source of the dust, wind, 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 is more than 80%. If combined with a water spray system, the dust suppression rate can be over 95%. At present, it is a major dust pollution control technology being applied.
