The MQi Dry Analyser is used for the in-line measurement of dry free-flowing streams with grain sizes below 2mm.
Measure
The scanner head is designed to receive a free flowing ore stream vertically downwards. Mineral grade, elemental grade and particle size are measured in-line and in real-time.
The technology used is inherently safe and based on diffused reflective spectroscopy combined with proprietary chemometric techniques.
MQi Dry Analysers are suitable for installation in any plant environment and in process lines of any diameter.
Control
The data in the graph below originates from a typical application in the heavy mineral sands industry. Data made available by an installed MQi Dry Analyser is shown for step changes on a high tension roll (HTR) separator. These changes were initiated through changing to the corona wire high voltage settings.
Through the manipulation of the voltage, it is therefore possible to control the product grade in real-time through the data made available by the MQi Dry Analyser.
Optimise
With the availability of the real-time data, it is possible to track the effect of process changes on the grade without full plant surveys.
Product grade can be optimised and impurities minimised. All in real-time.
