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?
RAJESH
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
