• Despite the similarity of the production path of micronized gypsum with ordinary gypsum, the presence of a separator changes the final result in an incredible way. • This engineered and modern system has taken the production of micronized gypsum powder to a different stage. This difference makes it possible to produce gypsum with the requested initial setting time according to the customer's order. • Micronized gypsum granulation is in the micron range (below 200 microns = 0.200 mm) which is used for polishing (smoothing and polishing the final gypsum surfaces) as well as for gypsum cutting and tooling in the construction industry. • Razi micronized gypsum with Ronak brand can be produced in 100, 150 and 200 meshes, in 25, 30 and 40 kg bags made of propylene and Adstar and is offered to domestic and foreign markets.
