  • Pneumatic jig: effect of airflow, time and pulse rates on ...

    2018-1-21 · In general, the pneumatic jigging movement depends on two important factors which are airflow rate and pulse rate. The former lifts the bed, and the latter creates intermittent air current. Airflow rate, pulse rate and time were studied to identify the significant parameters affecting separation efficiency in pneumatic jigging.

    David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Conveying air requirements. The differences in minimum conveying air velocity values that can be used for the three material types result in totally different conveying air requirements. These are shown in Fig. 15.2.This is a plot of material flow rate against air mass flow rate and is drawn for a 200 m long pipeline of 75 ...

  • Conveying Air - an overview

    David Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. The influence of airflow rate. The velocity of the conveying air will be approximately proportional to the airflow rate, whether on a mass or a volumetric flow rate basis. Equation 10.2 shows that pressure drop is proportional to the square of the velocity, and so airflow rate will have a very significant effect on ...

If, for some reason, system requirements are uncertain, then an improper guess at fan rotational speed can cause under-performance or excessive airflow and pressure.
