Afterwards, the clinker is finely ground by ball milling with a small amount (typically 5%) of gypsum/anhydrite to give Portland cement. Gypsum/anhydrite is introduced to control the initial rate of reaction with water and to allow concrete to be placed and compacted before hardening commences. Blended cements are produced by intergrinding cement clinker with materials like fly ash, granulated ...

mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion. As shown below, "mill energy specific ...

calcining plant, and not all cement components in the MVR mill, must be processed at higher temperatures. A positive side effect of this procedure is that, if the gypsum calcining plant is suitably adjusted, a silosafe cement is produced. This prevents unwanted chemical reactions during storage, as well as the associated problems when the cement is discharged from the silo. Created Date: 3/23 ...
