Introduction to the Homogenization system of Cement Kiln

The rotary kiln made from MS Steel Plate, and Lined with firebrick. The Kiln slopes slightly (1-40) and slowly rotates on its axis at between 30 and 200 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of kiln causes it gradually to move and go down to the other end of the kiln. At the other end fuel, is blown in through the burner, producing a large concentric flame in the lower part of the kiln. As material moves under the flame, it reaches its peak temperature, before dropping out of the kiln into the cooler.

Features and applicable enterprise:

Continuous homogenization system is featured with simple operation, convenient management and operation, easy automatic control. But the homogenization effects of Intermittence homogenization system are pretty good. Homogenization system of cement kiln is determined by the following factors: fluctuations of the raw material constitute, the scale of factory, automation control level and the requirements for quality of rotary kiln raw material. When the fluctuation of raw material constitutes is little especially there is no preblending bed factory, you can adopt continuous homogenization system and automation control level to this system. When the fluctuation of raw material constitutes is big, the small and medium-size enterprises with low level of measurements control equipment should adopt intermittence homogenization system. In addition, more material circulation homogenization base, multi-base collocation and mechanical type have also been regarded as the homogenization approach of small-size cement kiln enterprise.

Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. This is an important discipline, because heating up and cooling down are long, wasteful and damaging processes. Uninterrupted runs as long as 18 months have been achieved.
