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.

Typically the kiln is driven at speeds of 0.5 to 2 RPM, often with variable speed arrangements. Typical transit times for the lime through the kiln are from 1.5 hours to 4 hours under normal operating conditions. This is set by the speed and by the slope of the kiln, which is between 1.5° and 3° (5/16 to 5/8 inches/foot).

Cement mill - Wikipedia

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.


11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites.
