High Exit vent temp at cement mill outlet - Page 1 of 1

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.

cement mill outlet cement temperature

The slurry is fed into the kiln at the upper end and pulverized coal is blown in by an air blast at the lower end of kiln, where the temperature is about 1450°C. The coal used in kiln must not have too high an ash content because 220 kg of coal is used to make one tonne of cement. It is worthy when considering the amount of cement.

Nov 02, 2015· High Exit vent temp at cement mill outlet. We have open circuit ball mill grinding OPC 43 grade, feed moisture 2% max, Inlet temp 35 Deg C and outlet temp we are getting around 90 to 95 deg C, what could be the reason of high temp at mill outlet, since we have not supplied hot gas at feed, can anybody suggest the possible reason please, which helps to take necessary action.

Accident at the cement plant : CatastrophicFailure

This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
