Lime kilns are usually inclined at about 3°-5° slope with material charged at the elevated end and discharging at the lower end. The degree of fill is relatively deep, about 10-12%. Owing to its low thermal conductivity, limestone with a large diameter of about 2 in (5 cm) results in higher effective bed heat conduction than smaller stones.
