A well-performing kiln does not just happen. It is the product of well-engineered and reliable components, mixed with an expert understanding of the cement-making process and long years of experience in the design, installation and support of rotary kilns around the world. Not many companies have all three. But we do.
The present study develops a one-dimensional kiln model using elements of existing models and then links the model to the surroundings via a composite resistance …
Simply effective kiln optimisation. Since its launch in 2003, the KilnLoq gas analyser system has become the preferred probe system for the cement industry. Typically used in kiln inlets and calciner exits, the KilnLoq probe is designed to withstand the harsh, high-temperature environment of your pyro process.
The kiln length predicted by the present model is 5.74 m as compared to 5.5 m of the pilot kiln used in the experimental study of Watkinson and Brimacombe (1982, Watkinson, A.P. and Brimacombe, J ...
The clinker discharged from the rotary kiln enters the rotary cooler and is rapidly quenched with water from 1,400°C to 600°C. The clinker subsequently passes through the roll crusher, which produces grain …
