A Method for the Evaluation of the Required Flow Rate of Aspirated Air for the Reloading of Loose Materials in Telescopic Plants

On the basis of the hydrodynamical equations for the ejected and recirculated air flows in systems of loading telescopic tubes and bypass chambers, we propose a method for the evaluation of the flow rate of air entrained by the loose material and the required flow rate of aspirated air. It is shown that the energy consumption of the aspiration-technological units of telescopic plants can be significantly reduced by using coaxially arranged charging telescopic chutes with corrugated impenetrable walls placed around them and with the help of sealing of the neighboring upper and lower shelters.
