The usual quality determination of the mineral in calcination processes includes problematic sampling, sample preparation, analysis and reporting, followed by an interpreted input into the process control system. This control cycle, apart from the errors that may be incurred, takes at least three hours. Operators have a challenging task to interpret the results: both taking action when necessary but also ignoring spurious outlier results. Underlying trends only become apparent after several sampling-and-analysis cycles.
The MQi High Temperature Analyser is used for the in-line measurement of high-temperature calcination processes. This new solution combines three principles that enable industries to make informed decisions fast, so you can optimise your product grade in real-time.
Measure: The Blue Cube High-Temperature innovation for the patented MQi is achieved by placing a robust optical probe in a strategic position to view the calcined product. It projects an incident flashlight beam and collects the reflected spectral in the ultra-violet, visible and infra-red ranges data several times per second.
Control: The spectra obtained are compared to the calibrated signature spectrum of the desired product.
Optimise: The deviations are then used as inputs to the process to achieve the desired product quality consistently.
