This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use. 4) Hydrating In this step, hydrated also known as slaked lime is produced by reacting quicklime with water. CaO + H2O → Ca (OH)2

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.
Vertical lime kiln is also called vertical kiln lime or vertical shaft kiln for lime. It is a vertical static device for the decomposition of limestone to produce quicklime/burnt lime. Vertical lime kiln is suitable for projects with smaller quicklime capacity for its low cost implementation.
