Cement Kiln

New dry-process cement production line mainly consists of preheater, decomposition furnace, rotary kiln, grate cooler, three air ducts are composed of several systems, their respective areas have different working characteristics and use of the environment, new dry-process rotary kiln due to process characteristics caused by alkali, sulfur and other volatile components of the enrichment, the kiln temperature, kiln diameter increased, kiln speed accelerated, the structure of the complexity of the reason, resulting in the refractory material of the chemical attack, high temperature damage, mechanical stress and thermal stress and other comprehensive crushing effect is greater than the traditional kiln. Stress and thermal stress and other comprehensive crushing effect than the traditional kiln is greater, coupled with the current higher environmental protection and energy saving requirements, should be based on the characteristics of the working conditions, each region should be selected from different refractory materials.

The thickness of refractory bricks should be within a reasonable range, its life is not proportional to the thickness, for the expansion coefficient of the refractory bricks, too thick lining due to the temperature difference between the inner and outer layers and the expansion of the amount of the difference is too large, often lead to early damage to the inner layer of the work!
