Modelling and optimization of a rotary kiln direct
2014-8-5 · rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.

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.

degree of kiln filling Page 1 of 1
Degree of kiln filling means volumetric filling percentage of kiln charge inside the kiln (i.e. charge volume divided by kiln volume).To get the heat transferred into the ineterior of the charge it is an advantage to get a low degree of filling in the kiln.For this reason it is often an advantage to use a high kiln speed, despite the reduce residence time of the clinker in the burning zone.The desirable range is 13-14%.The dgree of filling in the kiln
