How kiln production varies with Kiln RPM?

With variation of kiln rpm kiln volumetric filling %, will also be changed.Normal range of kiln volumetric filling is 13-14% and it can be calculated by the following formula:

Kiln Degree of filling DF     3.2 * P/Deff 3 * n * s
  %   Where; 
      P Clinker production, tpd
      Deff Burning zone effective diameter, mts
      n Kiln speed, rpm
      s Kiln slope, %
