Optimization study on the application of induced dust suppression cover in primary crushing station of open-pit mine

Aiming at the problems of large dust production, high removal cost and poor suppression effect primary crushing station in open-pit mine, new type dry device-dust cover was put forward, which induced to complete circular clean movement with closed loop eddy current inside enclosure by means pressure balance flow. After field application, it found that device not ideal seriously affected wind. By fluid dynamics simulation, structure optimized for design engineering application. The simulation results showed enhanced overall upward trend internal air flow, weakened transverse blocked interference ambient wind, can effectively inhibit driving overdraft on dispersion. monitoring concentration around significantly lower than before optimization, lowest reach 0.33 mg/m3, met requirements environmental protection emission.
