• Kiln Speed - Page 1 of 3

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.
