Rotary kiln dust away the heat loss in wet kiln 12.71 kcal / kg of clinker, semi-dry kiln is 35.55 kcal / kg of clinker, accounting for 1-4% heat consumption, although this loss not much, but can not be ignored. Because cement kiln emissions concentrations exceeding national standards, pollution is very serious, for many companies spend part of every year as compensation funds, although compensation solve the problem, but the environmental pollution caused by the loss is immeasurable, but not money can make up, so that the reduction kiln dust, improve the environment is already present, the most important thing. Reduce heat loss kiln dust, one is to reduce the amount of kiln kiln dust to escape, the second is a reasonable treatment kiln dust, current in addition to all the dry kiln feed from outside the kiln, wet kiln processing method, although much, but enough for Some users of the kiln dust mixed into the raw meal with a dry kiln calcination, some mixed with a small amount of ash in the kiln clinker production part masonry cement, and some consider the use of shaft kiln, this problem has been lead to relevant departments under study and experimentation.
