As with the PFR kiln, the kiln charge consists of crushed and screened limestone or dolomite. The grain sizes are typically 40 to 80 mm or smaller. The kiln shafts are also completely filled with the material to be processed but the kiln charge passes the lime kiln at a higher speed - typically two meters per hour.
Black-mix is made to nodules of size 6 — 8 mm before feeding to kiln with 12 to 13 % water or 0.13 x 1.63 = 0.212 kg water/kg clinker and this is the reason for manufacturing process is termed as semi-dry process. Kiln exhaust gas quantity remains as 2.29 kg with an average density 1.825 Nm³/kg. Material & Heat balance to produce 1 Kg ...

Abstract. single vertical shaft lime kiln was modeled, designed and operated based on the phenomena controlling the calcinations reaction of a limestone source (Jakura limestone found in Nigeria). The kiln showed a thermal efficiency of 61% and calcinations efficiency of 83%. The results agreed well with the prediction of the calcinations model.
