The instrumentation currently installed at Codelco, El Teniente Division (DET) for dry particle size measurement (conveyor belts) is based on 2D image analysis technology providing a good and reliable approach for the operational control of grinding processes.
Objective and scope
Identify technological solutions that allow simultaneously, online and in real time, the measurement of particle size and provide information to estimate the mass flow rate in conveyor belts. A unique solution is sought to determine both variables.
The proposed technological solution must consider the following requirements:
Consulting and engineering studies will not be considered in the evaluation process.
The incorporation of technology is required to make shut-downs less frequent (ideally eliminate them) for
manual calibration of the belt scales.
When does the problem occur?
How is it currently resolved?
Technology has been tested to measure online particle size with 3D image processing.
