Cement Clinker Manufacturing Process with Reactions
Pure calcite in the kiln decomposes at around 650°C: 2 CaCO 3 + SiO 2 → Ca 2 SiO 4 + 2 CO 2 Reactive clay decomposition products and small amounts of alkali sulphate/chloride-melt draw the products together by surface tension and act as an ion transfer medium.

Types of Rotary Kilns
Such a kiln usually requires additional labor to attend the granulator plant. DRY-PROCESS KILNS. As the term indicates, in this process the kiln feed enters the kiln in dry powder form. Dry-process kiln dimensions are similar to wet kilns in that they are long and typically show a length-to-diameter ratio of approxi mately 30:1 to 35:1.

Manufacturing
The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water h…

A practical guide to improving cement manufacturing …
Cement manufacturing is the source of 5% of global CO 2 emissions. 60% of emissions are due to the transformation of raw materials at high temperatures and 40% results from the combustion required to heat the cement kilns 1400°C to1500°C. Therefore emissions monitoring is extremely critical for cement plants to meet regulatory requirements.
