justify this, retarder raw materials are used. In cement industry, natural gypsum (CaSO 4 ·2H 2 O) is the most effective raw material for this purpose. In the natural gypsum sources, anhydrite gypsum can often be encountered, so its effect on cement''s quality parameters must be focused on [13].

Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to .

It liberates a lot of heat during the early stages of hydration, but has little strength contribution. Gypsum slows down the hydration rate of C 3 A. Cement low in C 3 A is sulfate resistant. Tricalcium silicate, C 3 S:This compound hydrates and hardens rapidly. It is largely responsible for portland cement''s initial set and early strength gain.

gypsum role in cement grinding purpose of adding gypsum in the final cement grinding process. After gypsum and additives have been added, final grinding for cement production can take place in the cement plant, As in the raw material grinding process, our MCS plant control system plays a key role in optimizing the operational point.

Many in the cement and concrete industry know the role of gypsum as set retarder or set regulator. But the complementary role of gypsum, as accelerator to render high early strengths, is generally unnoticed. This knowledge gap lead to a misunderstanding that the addition of more gypsum means additional retardation in setting, which is not true.

During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter. Pure cement is formed when the cement clinker is ground into a fine powder. To regulate how cement mortar or concrete will set, gypsum is added to this powder.

Ramachandran elaborates on the gypsum demand and supply scenario in India. The Indian cement industry is the worlds second largest manufacturer of cement after China, ahead of developed nations such as the US and Japan. However India´s cement capacity is still far lower than China China´s capacity, which was 2020 mtpa in 2012.
