In the second half of the twentieth century significant advances were made which have culminated in the development of the precalciner dry process kiln. In this type of kiln, the energy-consuming stage of decarbonating the limestone present in the raw mix is completed before the feed enters the rotary kiln. The precalcination of the feed brings many advantages, the most important of which is high kiln output from a relatively short and small-diameter rotary kiln. Almost all new kilns installed since 1980 have been of this type. Figure1.4 illustrates the main features of a precalciner kiln

Observation 5; false air infiltration cold air entering the system via kiln hood, burner opening and casing. It either dilutes secondary air thus reducing recuperated heat or adds load to the waste air system of grate coolers and increase load on ID fan

Karapetyan also stated that changes in the tangential modulus of deformations of concrete samples matured both by regime I and regime II have the same qualitative characteristics similar to that observed in the case of strength

Besides the clinker phase composition, the presence of minor oxides may also affect the resultant cement strength. Among these, the effect of alkali oxides K2O and Na2O has been studied most extensively.177,182,400,421423 Unfortunately, even though a significant effect of alkalis on cement strength has been generally recognised, data on the character and magnitude of this effect are not uniform. Alkalis bound within the crystalline lattice of clinker minerals appear to act differently to those present in the form of soluble sulfates

Lower cost, more thoughtful service, increased equipment productivity and equipment performance.
