Dec 01, 2017 · When the predictions are out of range, advanced algorithms are used to prescribe operating parameters that could optimize the production KPIs. Using these parameters enable the variability in plant performance to be minimized. Thus a cognitive cement plant is run at optimal performance irrespective of raw material or environmental variants.
Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.

May 31, 2019 · PDC Bit Operating Parameters. Last Updated on Fri, 31 May 2019 | Drilling Engineering. PDC bits do not have the benefit of the self fluid-cleaning action between rows of teeth like roller cone bits, so they must rely on the bit's hydraulics to flush the cuttings from under the bit to prevent balling. This is accomplished with strategically ...
