Apr 01, 2016 Gypsum is a crystalline form of hydrated calcium sulfate (CaSO 4 2H 2 0) generally used in cements and plasters in the construction industry, though also in paints, fertilizers, medicines, papers, and textiles. For use in these materials, gypsum must be ground finely ( 100 μm), if not ultra-finely ( 10 μm), for which ball mills are most effective.

Alpha calcium sulfate hemihydrate having an average particle size of 50 microns was introduced into a ALPINE Super-Orion-Kugelmuehle, a ball mill of Alphine AG, Augsburg, continuously at the rate of 700 kilograms per hour. The ground product showed an average particle size of 2.4 microns and an Enslin factor of 0.70 milliliters of toluene per gram.
Apr 01, 2016 When gypsum is heated, it loses approximately three-quarters of its water and becomes hemihydrate gypsum (CaSO 4 H 2 O), which is soft and can easily be ground to a powder called hemihydrate gypsum plaster or plaster of Paris. If the powder is mixed with water to form a slurry or paste, it will dry and set rock hard.
The hydration of an anhydrite of gypsum (CaSO4.II) in a ball mill was studied as a function of time and temperature. The amount of gypsum formed at different intervals of time was determined by.
Jul 10, 2019 Post grinding in our ball mill gives our hemihydrate very fine particle sizes, 90 at less than 63 m,” he says. Replicating this success in Richards Bay Goudriaan says that negotiations are at an advanced stage to replicate this model in Richards Bay, where a 700 000 to 1 300 000 t annum of dihydrate resource is available.
Mould plaster has better intensity than building gypsum does, it's used for modeling, sculpture, decorate area. A type hemihydrate gypsum could be fine grinded to get high intensity gypsum. This gypsum has high degree of density and intensity. Gypsum could be.
What is claimed is 1. A process for producing an accelerator for hemihydrate gypsum comprising comminuting gypsum board to a particle size of about 100 mesh, and thereafter fine-grinding the resulting comminuted material in a ball mill to have an average particle size of about 1 micron and to have a specific surface area of about 100,000-130,000 square centimeters per gram.
