PROCESSING SOLUTIONS
cut benchmarks showing desirable data
ranges to quickly determine when equip-
ment and processes are abnormal. With
intuitive graphics, Mosaic's operators
can now understand the production data
in their HMI and are able to make more
informed decisions. Rather than a slew
of numbers, the new system showcases
useful information.
Additionally, the new system pro-
vides a simplifi ed presentation that uti-
lizes colors more strategically. Objects
are purposefully designed to blend into
the background so only important data
stands out. Alarm criticality is commu-
nicated by various color and shape com-
binations established by the PlanPAx
library. This prevents unwanted noise so
data can be processed quicker, further
improving operator productivity along
the way.
"Operators now have vital information
available at their fi ngertips — information
that any employee can quickly under-
stand and react to," Johansen said. "Our
long-term goal is to ease training and re-
duce downtime with a standard system
program across all our facilities."
The results, cautioned Rockwell, are
specifi c to Mosaic's use of Rockwell Auto-
mation products and services in conjunc-
tion with other products. Specifi c results
may vary for other customers.
Glencore Offers Online
Cell-size Calculator
Glencore Technology recently intro-
duced what it describes as the fi rst
accurate online calculator for estima-
ting which Jameson Cell is appropriate
for a fl otation circuit. The result shows
the size of the Jameson Cell installa-
tion needed to deliver any given tar-
get concentrate.
The free online calculator uses key
parameters such as commodity and cell
duty to decide what calculations are
needed. According to Glencore, it's then
remarkably thorough as it executes them.
It takes specifi c feed and concentrate
grades, recovery targets and percentages
of solids and builds each stage through
roughers, cleaners and recleaners, said
the Australia-based company.
The result is a powerful indicator of
what the recommendation could contrib-
ute to a fl otation circuit and to the down-
stream fl owsheet. It reveals what type of
Jameson Cells would deliver the outcome
and how many bubble-generating down-
comers would be required.
While it can't serve as a specifi ca-
tion without human interaction, not-
ed Glencore, it can help direct infor-
mation-gathering, planning and show
what's possible.
Virginia Lawson, Jameson Cell tech-
nology manager, said, "This is the fi rst
time an accurate online estimation tool
has been delivered to the market, and it's
incredibly insightful. I think many com-
panies have been coy to share this depth
of information, but there's no loss provid-
ed the indicator is meaningful."
