Ball Mill Synthetic Gypsum Plant

Following are the specifications of Ball Mill Synthetic Gypsum Plant:

Use : As a bounding compound.
Raw Materials : limestone, Sulphuric acid
CaCO3+ H2SO4 = CaSO4+H2O

Different form of synthetic or byproduct gypsum are now available for use and are being produced at economical rates which help the gypsum producers. In the business of making cement, gypsum costs usually very economical. Synthetic gypsum reduce costs as well as provide other manufacturing, environmental, and political benefits.

The few sources of synthetic gypsum are power utilities and acid neutralization. Many electric power utilities use high-sulfur bituminous coal as their source of fuel and in case of acid neutralization the chemical gypsum produced is of high quality, but it also is fine and wet, making it difficult handle.

Natural gypsum: CaSO4. 2H2O
Taking the example of synthetic gypsum manufacturing by power plant
As the power plant has the excess SO2 produced at the plant, these gases are called as Flue gases which are exposed to slurry of hydrated lime.

This lead s to the formation of calcium sulphite (CaSO3. A H2O)

This calcium sulphite is then oxidised to form the required gypsum. Of the formula of CaSo4.2H2O

The most popular source used is lime or limestone. In this process, when the slurry is precipitated, it results in a byproduct known as Flue Gas Desulfurization (FGD) material, or synthetic gypsum.
