    HISTORY OF THE ROTARY KILN

    The lime kiln Lime was usually produced in a vertical kiln Fig. 3. The process was operated batch-wise at the end of heating the charge, the kiln was allowed to cool and the product raked out. Naturally, this was a wasteful process due to the consumption of large amounts of fuel. In 1885, a patent was granted to Henry Mathey of

    A lime kiln is used for the calcination of limestone calcium carbonate to produce quicklime also called burnt lime. Usually, the heat is around 900 Degree Celsius, but a temperature around 1000 Degree Celsius is used to make the calcination process more quickly. Excessive temperature is discouraged because it produces dead-burned lime which is unreactive.
