clinkerization - an overview | sciencedirect topics

The cement manufacturing process includes the quarry, raw meal preparation, preheating of raw meal, kiln, clinker cooling, grinding, storage, and dispatch. In this process the calcium carbonate is heated to 900°C to decompose into calcium oxide (CaO, lime), and CO 2 is generated in the calcination process

portland cement clinker - an overview | sciencedirect topics

The free lime content of clinker is regarded as a practical measure of the degree of raw mix clinkerisation and is used as a means of controlling the quality of clinker produced. The typical range of free lime content in PC is 0.5–3%. Table 5.5 presents the free lime content in clinker manufactured with and without CS at different temperatures

impact of free lime on grinding efficiency - page 1 of 2

Aug 08, 2011 · Hello Pankajbits, All other factors being equal, low free lime clinker (hard burned) is generally harder to grind than clinker with higher free lime. This is due to physical changes in clinker mineralogy and porosity caused by over-burning rather than the presence of the free lime itself. Hard burning causes the following mineralogical changes which have a detrimental effect on clinker
