<p>The system and method for mix optimization in a raw mix process combine an on-line analyzer of material composition with a system controller which includes software for processing measurements and controlling flow rates of the raw materials used to make the raw mix. Periodic measurements by the analyzer generate a plurality of quality control parameters that characterize the raw mix composition. The system controller processes the measurements to generate an advanced control signal for each quality control parameter. The advanced control signals are generally defined ratios between functions of the flow rates to be applied to the different sources of the raw materials in the mix. Using the advanced control signals, flow rate set point values for the different sources of raw materials are provided to the local flow rate controllers. When deficiencies in the elemental composition of one or more sources makes it impossible to obtain the quality control parameter target, the system and method generate corresponding diagnoses and can use corrective sources to compensate for the deficiencies.</p> |
