Cement kiln refractories Understanding Cement

Cement kiln refractories Understanding Cement

+

Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern precalciner kiln system. The durability of the rotary kiln lining generally determines the duration of a kiln operating campaign.

Such a kiln is typically about 180 m long and 6 m in diameter, has a downward slope of 34%, and rotates at 12 revolutions per minute. (After Mindess and Young, Fig. ) Figure 32: Diagram of the reactions occurring in a typical dry process cement kiln without a preheater. The raw mix enters at the upper end of the kiln and slowly works its ...

Burning of these wastes in a cement kiln saves fossil fuels, as opposed to the necessity of using fossil fuels to ensure combustion of these wastes in an incinerator. Beneficial use is obtained in a cement kiln of persistent and toxic waste materials which normally require disposal.

There are wet rotary kilns, rotary kilns with grid preheaters and rotary kiln with cyclone preheaters (with or without precalciners). Wet process kilns are generally older than dry kilns. Long wet and dry kilns have only one combustion zone, whereas kilns with a precalciner have a second combustion stage upstream the kiln inlet.

The modern design of the plant, a cyclone preheater to increase the temperature of the solid input materials are used to shorten the length of the kiln. Raw materials to the kiln consist of calcium carbonate (CaCO 3), silica (SiO 2), shale (Al 2O 3) and iron oxide (Fe 2O 3) feeds. These compounds are very fine powder and mixed with cement to ...
