dc.description.abstractIt is now very-well known that mechanical activation can lead to dramatically changes in the thermal behaviour of many industrial minerals processed thermally for manufacturing a specific product. In this study, effects of intensive milling performed to generate mechanical activation on the calcination of gypsum, CaSO4.2H2O, to give hemihydrate, CaSO4.1/2H2O (plaster of Paris) was investigated. Gypsum samples were intensively milled in order to achieve mechanical activation using planetary ball mill with tungsten carbide media. Intensively milled samples were analysed using various kinds of instrumental techniques for characterisation of a wide variety of the properties like particle size distribution (PSD), specific surface area (BET), crystal structure (XRD), surface morphology (SEM), chemical structure (FT-IR), thermogravimetric (TGA) and thermal behaviour (DSC). According to the results, crystalline structure of the gypsum can be slightly deformed with increasing milling time, yet resulting in the decrease of the temperatures at which gypsum converts to hemihydrate and hemihydrate to anhydride (CaSO4). It was concluded that intensively milling creates mechanical activation yet enough to decrease the amount of specific energy needed for thermal conversions of gypsum.en_US
