The temperature of the grinding fluid, for example, has a pronounced influence on its heat removal capability. Salmon (1979) has shown that as the temperature of the bulk fluid decreases, the amount of heat removal and the power flux at bum increase (see fig. 7a and 7b). It is apparent from figure 7 that by reducing the fluid temperature from ...

Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength.

If the cement industry were a country, it would be the third largest emitter in the world. In 2015, it generated around 2.8bn tonnes of CO2, equivalent to 8% of the global total – a greater share than any country other than China or the US.. Cement use is set to rise as global urbanisation and economic development increases demand for new buildings and infrastructure.

Temperature control. Heat generated in the grinding process causes gypsum (CaSO 4.2H 2 O) to lose water, forming bassanite (CaSO 4.0.2-0.7H 2 O) or γ-anhydrite (CaSO 4.~0.05H 2 O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration. If more than this amount forms ...

3. Grinding: The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.
