History Of The Rotary Kiln Point

Rotary kilns have been synonymous with cement and lime kilns probably because of the history of their evolution and development It has been reported that cement deposits characterized by Israeli geologists in the 1960s and the 1970s place cement making at 12000000 BC when reactions between limestone and oil shale occurred during spontaneous combustion to form a natural deposit of cement
