Rotary kiln for lime processing

Qualified limestone are stored in the silo, then lifted to the top silo of the preheater by the elevator.The top silo of the preheater has two level indicators up and down to control feeding amount, and then by passing the filling pipe limestone is evenly distributed to each room of the preheater . Limestone in preheater is heated to about 900 ° C by kiln flue gas of 1150 °C, about 30% decomposed, pushed the rotary kiln by hydraulic push rod. The limestone in the Rotary kiln is sintered and decomposed into CaO and CO2.Generated limestone after decomposition reaches the cooler, in the cooler it is bubbled into the cold air cooled to 100 °C and discharged. Already heat exchanged 600 °C hot air reaches the kiln, mixes and fires with gas. The waste gas blended with the cold gets into the baghouse by the induced draft fan, and then by the exhaust fan reaches the chimney. Lime out of the cooler via vibration feeder, bucket chain conveyor, bucket elevator machine, belt conveyor is fed into the lime finished products warehouse. Then decide whether to go on the screening processes based on customers” requirements.
