· Normally drying is effected by ducting part of the kiln exhaust gas through the mill. Obviously a high drying requirement may be inconsistent with maxi- mizing the thermal efficiency of the kiln generally five and six stage preheaters are only employed where subsequent drying by the exhaust gas is minimal. Alternatively but less efficiently dedicated hot gas gen- erators can be used for drying in the raw mill.
