Analysis of cement

The basic principle of XRF analysis is simple. (The physics of what happens is complex, but we won''t concern ourselves too much with the details.) If we zap a sample of, say, cement with a beam of X-rays, the X-ray beam will cause other X-rays to be generated within the cement. Some of these X-rays escape from the cement and are collected by a ...

The cement kiln

A development of this process is the ''precalciner'' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
