Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.
Function: A cement mill is a drive used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

The flowsheet diagram of the wet process for manufacturing Portland cement is given in Figure 3.3. The limestone is disintegrated in crushers. The crushed limestone is fed to a tube mill, where the limestone and the clay, introduced as a slurry from a clay mixer, are simultaneously subjected to fine grinding.
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 method of grinding cement may also influence the hydration kinetics. Cements ground in high pressure roller mills set faster than in ball mills, because of higher reactivity of C 3 A and C 3 S phases, and a lowered rate of decomposition of CaSO 4. Figure …
In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone.
A Dry Type Batch Plant is a mixing plant that mixes large quantities of materials such as cement and water to prepare large batches of concrete. Dry batching plant is best suitable for construction projects wherein large amounts of concrete are required, such as highway projects, bridge projects, electric power plants, commercial concrete ...

Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker.
