Check out the benefits of O_Blend

AUTOPILOT to increase blend quality.

Visualize both tonnage and quality of piles and silos.

Sort the incoming material feeds.

What is it all about?

Based on on-line/at-line analyzers (e.g. PGNAA, at-line XRF, PFTNA, LIBS, NIR, Raman, particle analyzers), process measurement devices (e.g. scales, GPS), and off-line analyzers (e.g. lab XRF, GC, HPLC),
O_Blend helps

  • visualize the tonnage and quality of subpiles,
  • sort incoming material feeds onto subpiles,
  • optimize the quality of a blend batch (blendpile, train, ship, silo/bin) or a blend tonnage window by adjusting the proportions of the material feeders or reclaimed materials

in food processing/chemical/biotechnological/pharmaceutical plants, mines, ports, cement plants, power stations, where the quality can be a vector of product concentrations, moisture, grain size, CV, ash content, etc.

Various configurations

O_Blend is available for various industries such as:

  • O_Blend Cement for the cement industry,
  • O_Blend Coal for coal-fired power stations, coal mining, and terminals,
  • O_Blend Mineral for ore mining and metallurgical plants (iron, copper, phosphate, nickel, manganese, etc.),
  • O_Blend Food for the food industry,
  • O_Blend Glass for the glass industry.
O_Blend Features


    • Visualize tonnage and quality maps of stacked (sub)piles
    • Assist in selecting the sources of the incoming material feeds
    • Assist in optimizing the subpile cuts to reclaim by predicting the quality of the reclaimed materials


    • Automatically sort or assist in sorting an incoming feed from a truck, train, ship, quarry or mine onto subpiles with distinct grades


    • To reduce the variability of blend quality, automatically blend or assist in blending several material feeders or reclaimed materials
    • Handle large unknown variations of the material qualities with no need to update the qualities 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/reclaimer actions and off-line analysis in the absence of an on-line/at-line analyzer
    • Apply customized strategies to reduce the effects of silo or pile changes and large perturbations in the feeds
    • Use alternative feeds when a feeder/reclaimer reaches a limit
    • Apply customized strategies e.g. to handle feeders/reclaimers with a nonzero minimum flowrate or when a feeder/reclaimer deviates from its setpoint
    • Compute an optimal raw material or subpile for each feeder/reclaimer
    • Use transparent feeder/reclaimer actions

And more:

  • Reduce the need for recalibrating on-line/at-line analyzers
  • Fast commissioning thanks to a dynamic simulator
  • Maximize the throughput of mills
  • Connect easily to a customer PLC (ABB, Rockwell, Schneider-Electric, Siemens, Yokogawa, etc.)
  • Plant automation and SCADA available such as server/client set-ups with operator panels and manager PCs for reporting.
A sucess story

O_Blend has been successfully implemented worldwide.

”We have used O_Blend 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 as an excellent system.”
