Cement Mill Exit Temperature Standards

  • Cement mill Wikipedia

    A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

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

  • Cement kiln Wikipedia

    heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel.

Dust [which includes (Total Suspended Particulates (TSP), Particulate Matter smaller that 10µm (PM10) and Particulate Matter smaller than 2.5 µm (PM2.5)], SO2, NOx and CO are expected to exit from the raw mill and kiln stack. Dust is the only expected emission from the cooler stack and the cement mills stack.

    High milling temperature causes this. On the other hand, if milling temperature is too low, insufficient rapidly-soluble sulfate is available and this causes “flash set” an irreversible stiffening of the mix. Obtaining the optimum amount of rapidly-soluble sulfate requires milling with a mill exit temperature within a few degrees of 115°C.

  • Cement Types

    What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.
