cost impact on manufacturing; therefore, variation is generally accepted. The calcination temperature should be controlled very closely. To heat the limestone evenly in the kiln, the particle size of feed must be relatively uniform. To avoid long residence time in the kiln, the particle size of limestone must be small, typically about 1 ½".
