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

Working with the Materials Processing Institute (MPI), the team trialled replacing the usual lime flux with used cement. They separated the resulting hot liquid slag that floats on the surface of molten steel during recycling and then cooled it to form a powder. They then mixed this with gypsum and cast it into cement samples.

The conclusion is that, for a cement plant with a raw meal feed of 335·5 t/h and the addition of 1500 m 3 /h of oxygen, 8% more fuel can be added in the calciners. This allows for a 116% addition of raw meal while maintaining product quality. Another consequence is that the temperature profile of the process changes.
