    Jun 18, 2020 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

    The produced clinker varies in reactivity depending on many factors as for example the quality of the limestone, the conditions in the kiln etc. If a more reactive clinker is produced, the clinker part in the cement could be more diluted. It would still have the same quality as the cement made of less reactive clinker but the CO. 2

    That this is indeed the case is the daily experience of every kiln operator. On the other hand, Model 1 implies a massive exothermic reaction which, once started, is sufficient to cause the feed to heat up spontaneously by 200-300 C. Starting at 1300 C, this would produce molten clinker (and probably molten brick and kiln shell)

    Re: Chloride. There is no direct relationship between kiln feed, hot meal and clinker chloride content except to say that as long as you are not regularly venting chloride from the kiln system eg via a bypass, or by removal of frequent chloride-rich buildups, or via dust escaping from the stack... input must equal output. Chloride volatility (and therefore hot meal chloride content) is influenced by the presence of
