Such calcining system further includes a first damper mounted in a duct for discharging the exhaust gas from the raw material preheating device, a temperature sensor for sensing the temperature of calcined material discharged through an outlet of the planetary cooler, control device for controlling the degree of opening of the first damper when the temperature sensed by the temperature sensor rises to a high level, a second damper mounted in the air extracting duct, a gas sensor for sensing a gas component capable of indicating the condition of combustion in the rotary kiln, and control device for controlling the degree of opening of the second damper so as to bring the value of the gas component sensed by the gas sensor to a predetermined level. The flow rate of the cooling air can be controlled independently of the control of the flow rate of the air combustion, so that the temperature of the calcined material at the outlet of the planetary cooler can be kept at a predetermined level selected arbitrarily and the combustion in the rotary kiln and the calciner can be stabilized irrespective of changes in the conditions of operation.
