3 CEMENT PRODUCTION PROCESS AND ENERGY USE 3.1 INTRODUCTION Cement is an inorganic, non-metallic substance with hydraulic binding properties, and is used as a bonding agent in building materials. It is a fine powder, usually gray in color, that consists of a mixture of the hydraulic cement minerals to which one or more forms of calcium sulfate have
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

Apr 13, 2020· The Fig.1. show the flow diagram of the dry process of the manufacture of cement. 1. Dry Process. In the dry and semi-dry process the raw materials are crushed in a dry state. Then, they are processed in grinding mill, dried and reduced to very fine powder-like. That dry power is further blended, corrected for the right composition and mixed
40% more cost intensive in cement production than the dry process while at the same time it is cost effective to run production on energy through gas powered plant than the national grid. Material and energy flow diagram for dry process manufacturing of cement. Figure 2. Material and energy flow diagram for wet process
Chapter 3 provides an overview of the cement production process and an overview of main environmental matters in the cement industry. It describes the main sub-processes involved in cement production and defines the group of sub-processes which is to be covered by the BAT Reference Document for the cement sector.
