Topic: Re: Calculating kiln residence time

posed by 
Residence time in the kiln will not be easily calculated unless you have data that indicates the hold-up in the unit. These units are typically designed with baffles to afford additional hold-up, and this data coupled with “angle of repose” data for the solids being handled will allow an estimation of the residence time. The calculation is straightforward once you know what the total rotary kiln holdup is (holdup/rate).
