The large scale and high strength vortexes in front of the wind-proof dust suppression net are attenuated and carded into small scale and weak strength vortexes. After passing through the wind-proof dust suppression net, only part of the wind passes through the wind-proof dust suppression net, and its mechanical energy attenuates and becomes low-speed airflow.

Railway Sand And Wind break Steel Fence is the most advanced technology for dust pollution control of open bulk storage yard. It is widely used in coal yard and material yard pollution control of port, traffic ,coal power generation, coal mine, coking, steel, coal washing, cement and other enterprises.Make full use of the principle of aerodynamics, the product to effectively control the source of dust, wind, maximum attenuation to the kinetic energy of wind flow, reduce the dust and dust with ability, thus suppressing the effect of dust, comprehensive wind dust suppression rate can reach more than 80%, has now been applications as the main management technology of dust pollution.
