    Apr 12, 2009 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

    Ventilation Prediction for an Industrial Cement Raw Ball

    In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named “conscious laboratory (CL)”. For constructing the CL, a
