Check out the benefits of O_Blend CEMENT
Master strongly varying raw-material compositions during blending in cement plants.
Sort the incoming raw-material feeds.
Ease recalibration of on-line analyzers.
Increase raw-mill production.
Based on on-line analyzers (e.g. PGNAA, PFTNA, LIBS) or off-line analyzers (e.g. XRF),
O_Blend Cement
helps
-
visualize the tonnage and quality of stockpiles and silos,
-
sort an incoming feed onto stockpiles with distinct grades,
-
optimize the quality (e.g., targets for LS, SR, AR; upper limits for Fe2O3, Al2O3) of a blend batch (blendpile, train, ship, silo/bin)
or a blend tonnage window by adjusting the proportions of the raw-material feeders or reclaimed materials,
-
optimize the raw-mill throughput.
-
Visualize tonnage and quality maps of stacked (sub)piles and predict the quality of the reclaimed material
-
Sort automatically or assist in sorting an incoming feed from a train, ship, quarry or mine onto stockpiles with distinct grades
-
To reduce the variability of blend quality, automatically blend or assist in blending several raw-material feeders or reclaimed materials
-
Handle large unknown variations of the raw-material compositions with no need to update the compositions by the user
-
No need for maintenance contract or on-site expert as O_Blend is based on novel measurement-based optimization (MBO) technology
-
Compensate for large time delays (40 min and more) between feeder actions and XRF analysis in the absence of an on-line analyzer
-
Apply customized strategies to reduce the effects of stockpile or silo changes and large perturbations in raw materials
-
Use alternative feeds when a feeder reaches a limit
-
Adjust production when a feeder deviates from its setpoint
-
Compute an optimal raw material for each feeder
-
Use transparent feeder actions
-
Maximize the raw-mill throughput
-
Reduce the need for recalibrating on-line analyzers thanks to Compensator module
-
Fast commissioning thanks to a dynamic simulator
-
Connect easily to a customer PLC (ABB, Rockwell, Schneider-Electric, Siemens, Yokogawa, etc.)
Online Control Ltd.
is based in Lausanne, Switzerland. O_Blend Cement has been implemented successfully worldwide
for stockpile and raw-mill applications.
Happy customers include: Holcim, Cemex, Titan Cement, Chettinad Cement, Scantech.
”We have used O_Blend Cement 24h/day 7days/week. After
commissioning in 2009, the quality of our production has increased. In
conclusion, we are very happy.”
”We consider O_Blend Cement as an excellent system.”
