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

02/11/2015 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.

Cement Kilns: Exhaust gas handling

For this reason, in order to maximise the kiln output, it was necessary to maintain a high exhaust gas temperature, and this was a dis-incentive to improve energy economy. A 20 m kiln would not work with an exit gas temperature less than around 600°C, and for

The Cement plant in Jakarta, Indonesia with a capacity of 7800 TPD, planned extensive use of alternate fuels in the kiln. This was leading to excessive Preheater exit temperatures up to 4300C and was limiting the fan capacity. Hence, they needed a gas cooling system before the fan to reduce the temperature by 500C so that the plant production level is maintained/enhanced as required.

What is Cement Clinker? Composition, Types & Uses Civil

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
