The heart of a lime plant is the kiln. The prevalent type of kiln is the rotary kiln which accounts to about 90 percent of all lime production in the world ( Ellis 1960 ). The kiln is a long, cylindrical, slightly inclined, refractory- lined furnace, through which the limestone and hot combustion gases pass counter currently.
Rotary kilns employ high temperatures to cause a chemical reaction or physical change in a material. In most cases, these high operating temperatures would immediately destroy an unprotected carbon steel shell. For this reason, refractory is used.
Work on the lime kilns was arduous, hot and dusty. The gases leaving the top of a continuously operating kiln must have made manual charging an exhausting and unpleasant operation, although the top layer was cool. Gas leaving a coal fired kiln was not toxic but could induce nausea, a characteristic put to good use earlier this century by the ...
Under the same conditions, the activity of lime produced by rotary kiln is higher than that produced by gas kiln, with an average of over 30 ml. The activity of lime produced by rotary kiln is generally 340-380 ml, or even up to 400 ml. 3. Rotary kiln can directly calcine 10-50mm fine-grained limestone.
