Active lime is produced from limestone dolomite chalk and other minerals with high calcium carbonate content by the calcination process under the temperature of 1000-1100 ° C. There are various processes for the active lime production mainly including: Advanced 'Preheater-Rotary kiln-Vertical cooler' energy-saving process Traditional 'long rotary lime kiln' process Mixed buring vertical kiln process Gas-ﬁred or oil-ﬁred vertical kiln process. The selection of the active lime process is effected by many factors such as : the activity requirement the fuel the limestone sizes production capacity environmental-protection requirement.
Mixed Burning Vertical Lime Kiln Process
The qualified raw materials and solid fuels are mixed uniformly according to a certain proportion and then sent to the vertical kiln through a single bucket elevator for calcination. After calcination, the final lime products are discharged from the bottom of the vertical kiln through a discharge device to the conveyor, and the conveyor sends the final lime products to the storage silo. The hot flue gas generated by calcination will firstly go into the dust collecting system, and then the clean flue gas will be emitted through chimney to the atmosphere.
