Gypsum is a mineral occurs naturally and is basically is a sulphate salt. Rajasthan produces 99% of the total mineral Gypsum production in India. And most promising deposits occur in Bikaner Distt. As demand is increasing so there is the need for prospecting new promising areas of Gypsum. In the deposit, Gypsum ore is found to be present as a soft sulphate mineral composed of calcium sulphate dihydrate. The chemical formula of Gypsum is CaSO4·2H2O. Gypsum in India occurs in lumpy form and needs crushing and grinding to obtain Gypsum powder. It is mostly used in powder form.
Processing of the ores is required to produce industrial Gypsum powder products and. Gypsum mining equipment includes gypsum crusher, gypsum mill, and other gypsum equipment.
Gypsum powder manufacture
Gypsum powder is extensively used by cement industries, paper making, painting items, as well as for decoration and soil concentration, therefore, we need different processing technic to follow for Gypsum, but the physically processing routes are identical.
The first activity is blasting for exposing the Gypsum layer. Then it is conveyed to the crushing stage: Gypsum lump ore is fed into the primary crushing plant and gets crushed goes for the heating process.
Gypsum is heated at different temperatures and to produce a different grade of industrial materials. Heating at 128℃ makes it the important cementing material. With further heating at temperature 163℃, it produces anhydrite Gypsum whose chemical and physical property is constant.
Gypsum processing Equipment: It comprises of Gypsum crusher includes jaw crusher, cone crusher, impact crusher and mobile crusher, Gypsum designed with high technique with world first-class level. To produce a coarse powder. The mills are, ball mill, high pressure grinding mill and vertical mill, etc. Gypsum vibrating screen is the ideal screening equipment. Gypsum vibrating screen purify gypsum quarry from soil impurities. Gypsum belt conveyors which are rubber belt conveyor and which can work for a wide range of temperature.
Gypsum powder exporters in India
India exports Gypsum powder mostly to cement industries located abroad. Gypsum powder exporter from India has a tendency of growth in view of demand of Gypsum by cement industries already operating. Demand forecast indicates that a good number of existing cement plants have an expansion plan. New plants are going to be commissioned by 2018 or early 2019. In view of this scenario, the companies who are already proved themselves to be a potential Gypsum powder exporter are examining the feasibility of increasing their Gypsum stock. Since 99% of Gypsum deposit is located in Rajasthan only, new exploration is going on to locate other potential deposits in Rajasthan. As per recent information, GSI already earmarked some areas in Bikaner, Rajasthan as a potential source.
Conclusion: From above information, it can be concluded that India has a great deposit of Gypsum ore. However, it is not adequate for meeting the intra Indian demands as well as projected demands from foreign countries. The potential client of them are U.S.A and UAE. New exploration is in progress and the prospect of availability of new deposits isencouraging.
