clinker production capacity of the rotary kiln is 65 th. Four stage cyclone type pre-heater is used to pre-calcinate the raw material before it enters the kiln. In a typical dry rotary kiln system, pre-calcination gets started in the pre-heaters, and approximately one third of the raw material would be pre-calcined at the end of pre-heating.
