Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
The cement industry can turn the waste problem into a value-creating opportunity by using the waste to substitute fossil fuels and natural raw materials: the co-processing. Co-processing is the use of waste material as raw materials or as a source of energy, or both, to replace natural mineral resources and fossil fuels such as coal, petroleum and gas in industrial processes.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
the cement industry planning process is centralized and optimization oriented. There is no constraint in the availability of cement main raw materials with the exception of some countries where subsoil ownership regulations applied. Cement manufacturing is capital and energy intensive where cement truck delivery is restricted due to its low
The cement industry can also take advantage of opportunities for industrial symbiosis – including using the waste or by-products from one process to produce another product of value – to help close the material loop, reduce energy use and reduce emissions in the case of carbon capture and utilisation.
more of the 3Rs, the cement industry provides the most resource-efficient alternative: of energy and material is recovered by co-processing waste in the cement manufacturing process. The following diagram shows the position of co-processing in the waste hierarchy.
THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie Ahmed Gad Faculty of Applied Science Chemistry Dept.

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.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.
