The small footprint (64-in. wide by
24-in. deep) coupled with mechanical
conveying to the analyzer and pneumatic transport of sample streams from the
unit minimizes installation problems.
Considering that the unit operates on
minus 4 mesh sample streams, this analyzer is most likely to be found in loadout towers, accepting either secondary or
tertiary reject streams.
The PRB mine discussed in this article actually tried out a prototype device
from Progression in 2010 and then
opted for a full production unit in the
fall of 2011. For a view of the installed
Titan CCA, see Figure 5.
As is typical of any established technology being applied to a new market,
there were some teething problems during commissioning. These issues, associated with a reliable air supply to the
unit, coal sampling, and network connectivity had been satisfactorily
addressed by early 2012. The unit has
been running reliably since then.
The PRB mine with the Titan CCA
uses it in both feedback and feed-forward modes. They use a rolling average
of online analysis results to detect
