Cement mill Wikipedia
Obtaining the optimum amount of rapidly soluble sulfate requires milling with a mill exit temperature within a few degrees of 115 °C. Where the milling system is too hot, some manufacturers use % gypsum and the remaining calcium sulfate as natural αanhydrite (CaSO 4). Complete dehydration of this mixture yields the optimum 2% γanhydrite.

Effective offgas temperature control without unwanted side effects can be achieved in many cement plants with stateoftheart evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of "dry" operation kilns. Evaporative cooling water sprays in conditioning towers,

Temperature monitoring across the manufacturing process is essential to support process efficiency and cement product quality. It can also help to prolong the life of the kiln through early detection of refractory issues or insufficiently quenched clinker, which could lead to production stoppages if left unchecked.

heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of the rawmix rises: 70 to 110 °C Free water is

As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both aircooling and watercooling, including spraying water inside the mill.
