History Of The Rotary Kiln

The lime kiln lime was usually produced in a vertical kiln fig 3 the process was operated batchwise 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
