cement kiln capacity calculation

Kiln Speed - Page 1 of 3 - International Cement Review

For calculating the kiln speed we require following details. The formula is. % of Filling Level = (3.2*production in tpd)/ (Effective dia of kiln^3*kiln slope*kiln rpm) Based on this universal formula in which all the cement plants use you can back calculate the kiln rpm based on what filling level your are maintaining. Regards, Maddy.
