Nov 21, 2015· The cement consumers in general and the practicing civil engineers in particular are greatly benefited by such competition Power: The blending of dry powders has now perfected and the wet process, which required much higher power consumption can be replaced with confidence
The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process
Wet process kilns 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
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicatOver a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant
