Approaching wind and dust walls, there are rows of small holes above, this appears to ventilate the wind blocking dust wall is how it? In fact, the use of new composite materials "net barrier" has been able to significantly reduce the amount of dust from the open-air coal pile, not rely on "Dust", the key is in the lower wind speed. The technology has been widely used in Europe, Japan and other developed countries, it is the use of aerodynamics, according to the scene is processed into a certain geometry, opening rates and different shaped hole combinations "net barrier" so that from the outside by strong winds When the wall on the inside of the wall forming the interference of airflow to achieve "outside of strong winds, the inside of the weak wind, outside of small wind, no wind the inside" effect, thereby preventing dust emissions.
