O_Blend Cement

Based on on-line analyzers (e.g. PGNAA, PFTNA, LIBS, NIRA) 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 input 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 input material feeders of stockpiles, raw mills and cement mills
• Handle large unknown variations of the input 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 O_Blend Cement Compensator
• Fast commissioning thanks to a dynamic simulator
• Connect easily to a customer PLC (ABB, Rockwell, Schneider-Electric, Siemens, Yokogawa, etc.)
