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

    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.

    Tips for Curing Concrete in Cold Weather

    The process of curing concrete becomes more challenging in cold weather since, to properly set and reach maximum strength, fresh concrete must be protected from freezing for at least the first 24 hours, or until it reaches a minimum strength of 500 pounds per square inch (psi). Concrete that freezes at an early age can lose much of its overall strength.
