CemenT Mill Ventilation Fan

WHAT SHOULD BE THE DESIGNED VOLUME & PRESSURE OF A CLOSE CIRCUIT BALL MII'S VENTILATION FAN ?

HOW THE FIGURES ARE ARRIEVED AT?

WHAT SHOULD BE THE DESIGNED DUST LOADING ON THE FAN?

PLEASE CLARIFY IN DETAIL..

ARE THESE SPECIFICATIONS ARE SAME FOR A SEPARATOR FAN ALSO?

IF NOT WHAT ABOUT SEPARATOR FAN?

Re: CemenT Mill Ventilation Fan

Designed volume for Cement Mill ventilation is function of Mill volume & will remain same for any capacity, however pressure will depend on system resistence.

Fan can be designed for dust loading of 3% & value can be derived from Euler's equation.

Separator fan dust loading normally depends on following-

1- Efficiency of  cyclones if in close loop

2- Efficiency of ESP or BH if in series
