Particle Density Meter(PDM)


The CleanProTech Particle Density Meter (PDM) provides the user a real time value of average particle density, which can be used to give an indication of the amount of saleable coal being lost in tailings. This greatly aids in optimisation of the flotation circuit as changes are monitored ‘online’.

No more waiting for laboratory analysis results!

Currently, the PDM is installed on flotation tailings but can be used to monitor other flotation streams. The PDM also has the ability to be adapted to monitor fine coal circuits such as TBS, Reflux Classifier and spirals.

If multiple PDMs are installed around a unit operation, you then have the ability to monitor performance online, including yield and cutpoint.

CleanProTech has also been working closely with Quality handling Systems (QHS) to design and develop a system which allows the PDM to operate on any conveyor belt stream. For example, if used on the feed conveyor, mining dilution can be monitored online, in real-time.

By monitoring important slurry parameters including solids concentration and slurry density, the PDM is able to calculate the average density of the particles flowing through the unit using a patented equation.
This average particle density value can then be used to monitor circuit performance, evaluate parameter changes and estimate the amount of saleable coal present in the stream.
