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 …
The prepared PBG was milled using a small horizontal ball mill. Two kilograms of the material were loaded into the ball mill each time. The ratio of PBG to balls was 1 : 1, and the samples were then grouped according to the duration of the ball milling process (10, 20, 30, 40, 50, 60, and 70 min), as shown in Table 2.
