Cement manufacturing is a major mineral commodity industry. In 1995 the world production of cement was 1,420 million tonnes. See Table 2.1 for geographical distribution. Total cement production in the European Union amounted to 172 million tonnes in 1995 ...
Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.
