Mining slurries

Since 2009, Rhosonics has been providing non-nuclear density sensors for use in the mining industry. As mentioned on the page about mining and mineral processing, many companies are currently using a nuclear device to measure density in-line. Rhosonics has developed a non-nuclear density meter for mineral processing: the Slurry Density Meter (SDM).

The SDM is recommended to measure the density of slurries and offers a lot of advantages due to the non-nuclear ultrasonic technology. No governmental licenses, permits or specialized personnel is necessary for the density meter because of the ultrasonic technology. Learn more about this product in our mining case studies.

In the picture below you can see some typical installation points of the SDM in a phosphate washing plant. These density meters are installed at the cyclone feed, cyclone outlet and thickener underflow pipe. Please click here to read the case study.

To avoid damage to sensors caused by abrasive media, we provide sensors that are installed with no intrusion in the pipelines. All sensors are flush mounted, which means that it is installed flat with the pipe surface. Ultrasonic signals are sent to the slurry and the instrument measures the acoustic impedance, which is the reflection of acoustic signals. The density is calculated by the electronics unit with a special algorithm. The SDM is mounted to the pipe using a “wafer”, "UFTP spool" pipe piece or a “weldolet” weld-on piece. The diameter of the pipe can be over 60 inch. Even the material of the pipe (rubber, steel, or steel with lining) is no issue for this ultrasonic technology. In consultation with Rhosonics, you can also choose a fixed tank-mount probe to perform measurements in a tank.
