Cement manufacturing process involves various raw materials and processes Cement is a greenish grey coloured powder made of calcined mixtures of clay and limestone When mixed with water becomes a hard and strong building was first introduced by a British stone mason Joseph Aspdin in 1824 who cooked cement in his kitchen He heated […]
Evolution of the cement Process • Wet process easiest to control chemistry & better for moist raw materials • Wet process high fuel requirements fuel needed to evaporate 30 % slurry water • Dry process kilns less fuel requirements • Preheater/Precalciner further enhance fuel efficiency & allow for high production rates

Manufacture Process of Cement The manufacture procedures of Portland cement is described below Mixing of raw material; Burning; Grinding; Storage and packaging; 1 Mixing of raw material The major raw materials used in the manufacture of cement are Calcium Silicon Iron and Aluminum These minerals are used in different form as per the
• Chalk is porous and often has high moisture content that leads it to its use in the semi dry/wet manufacturing process of making cement This particular process represents some 16% of total production Shale • Shale is a pure sedimentary rock made of very fine silt clay and quarz Shale falls in the category of mudstones
The detailed process of manufacture of cement is explained in Chap 4 The quality of cement is controlled as per the applicable standards These standards are prescribed by the authorized agencies and/or standard institutions in the countries In India the same is done by the Bureau of Indian Standards BIS
The report also provides detailed information related to the process flow and various unit operations involved in a cement manufacturing plant Furthermore information related to mass balance and raw material requirements has also been provided in the report with a list of necessary quality assurance criteria and technical tests

The cement manufacturing process involves 6 key phases 1 Raw material extraction through quarrying 2 Grinding proportioning and blending of raw materials 3 Pre heating of materials using hot gases from the kiln 4 Firing materials in a rotating kiln at 1450°C to form clinker 5 Cooling of clinker using forced air 6 Final grinding of clinker along with
The basic chemistry of cement manufacturing process begins with the decomposition of clay minerals into SiO 2 and Al 2 O 3 on the one hand and of calcium carbonate CaCO 3 at about 900 °C to leave calcium oxide CaO lime liberating CO 2 on the other hand The latter process is known as calcination

5 The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials mixing them in certain proportions depending upon their purity and composition and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C During this process these materials partially fuse to form nodular shaped clinker by broking
