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.
when grinding cement the layout is prepared with provisions for recirculation of hot exit gas to the mill inlet. In case the mill feed is wet slag or includes a significant portion of wet additives, additional heat must be provided, for instance from a heat generator. Other-wise, if the mill feed is very hot, the mill exit temperature

The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary cement is being ground, to 85-95% for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet.
